According to Dow Jones , some colleges have banned the iPad from their networks. Princeton and Cornell, for example, are seeing major networking and connectivity issues that mirror the problems many users are seeing with their iPads at home. Princeton also decided to share details about the issues it is seeing on its network in a detailed statement that could help Apple diagnose and fix the connectivity issues that have plagued the iPad since launch. Sponsor As we reported earlier this month, quite a few iPad owners have experienced WiFi connectivity issues with their devices. There seems to be a wide variety of issues, ranging from bad WiFi reception to regular drops on the WiFi connection because of what looks to be a bug in how the iPad connects to some routers. The iPad's Problem According to Princetion: DHCP According to the report from Princeton, at least one of these connectivity problems can be traced back to how the iPad handles DHCP leases. DHCP, which stands for Dynamic Host Configuration Protocol , is responsible for assigning IP addresses to computers on a local network. Normally, these IP addresses are renewed at regular intervals. If the device doesn't request a renewal of the address, the DHCP server can hand this address out to another device. The Princeton team found that, under certain circumstances, iPads renew their lease of a given IP address once but then allow the lease to expire. Once the lease has expired, however, these devices still try to use the same address without asking for a new lease, which is bound to fail, as the router doesn't remember the device anymore and has probably assigned the IP address to another device already. You can find more details about Princeton's diagnosis - as well as a step-by-step guide for reproducing this issue here . Is This Good News for iPad Owners? If this is indeed the source of most iPad connectivity issues, then this is good news for Apple and iPad owners who are currently experiencing these issues, as a straightforward software update can probably remedy this problem.

The enterprise may now have what they have wanted for the iPhone. But now they have to decide if such a locked down device is control they want secede to Apple We expect that Apple's tight control over its hardware, software and content will not stop an enterprise from purchasing the device. But it may cause some to pause and consider a smartphone with the Android OS - built on an open-source model with many of the same enterprise features that will come with the iPhone OS 4. In our post last week, we spoke with Ken Westin , CEO of ActiveTrak , who said the iPhone OS lacked multi-processing, SSL VPN, an and relied too much on MobileMe, making it troublesome for IT administrators. ActiveTrak allows for devices to be tracked if lost or stolen. Sponsor It looks like Apple checked most of the items off Westin's list except for one caveat. Multitasking work on the iPhone 3GS, its latest device but not the iPhone 3G. That actually may help sell a lot more phones into the enterprise. IT will want the multitasking feature, primarily for security purposes. As Westin points out, it's the multitasking that makes it possible for the ActiveTrak service to run in the background. With multitasking, ActiveTrak would not have to do any social engineering as is required wit the current OS. Currently, ActiveTrak is disguised as a Safari icon on the iPhone. The application activates when the user accesses the Internet from the iPhone. If it is not accessed, the device can not be tracked. But the Android has had multitasking capability since its inception so in this respect, it is not revolutionary for the iPhone to get such a feature. As for control, could an enterprise lose access to iPhone apps? This is not likely but as we have seen with Flash, Apple will make uniform decisions about what content it allows. The Android offers an open marketplace that has none of the restrictions that Apple imposes. Here's what is included in the iPhone OS 4: Multitasking ReadWriteWeb's Mike Melanson says the purists may not consider it multitasking but for most uses, it is close enough. He writes that multitasking, "for the most part, is handled by a double click on the home button, which pulls up a screen showing icons of all the apps currently hanging out in the background. Some, like Skype or Pandora, will actually be running, while others will simply be in a frozen state." Is that enough for an app like ActiveTrak? He said that from what he has seen so far, yes, it will suffice. Bit it is not something that puts it ahead of the Android. SSL VPN SSL VPN is now supported in iPhone OS 4. Apps are expected from Juniper and Cisco that will support SSL VPN, which allows for better way to securely access the enterprise from a browser across any device. Microsoft Exchange Email on the iPhone is now up to speed with the rest of the market. The iPhone allows a user to set up multiple Microsoft Exchange ActiveSync accounts. It also works with Microsoft Exchange Server 2010. Multiple email accounts may be pulled into one account or accounts may be viewed separately. Data Wiping and Mobile Admin Control IT administrators may now configure devices to update wirelessly. The device may be monitored to abide by corporate policies. It may be locked down if lost or the data may be wiped. Wireless App Configuration This would allow the control over what apps someone places on their device. According to Apple: "The iPhone OS 4 enables enterprises to securely host and wirelessly distribute in-house apps to employees over Wi-Fi and 3G. Apps can be updated without requiring users to connect to their computers. One thing we don't hear mentioned much is the lock down of the iPhone. Is it a major issue? It does mix into the whole scope of the app platform. So, we argue that it does. But, overall, we have to agree with the NextWeb. The difference between the iPhone and the Android in the enterprise might be best considered a draw: "Wireless delivery of applications, great data encryption, Exchange Server support. When you're in a business world, with today's technology, these things become expected. These are no longer seen as value-added features of any OS, mobile or otherwise. Now, in fairness, Android OS is not at the top of the Enterprise game. But neither is Apple. For years, RIM has set the standard. Even today, other companies have a lot of work to do in order to catch up. I have to call this an even draw." Discuss

Should college students consider buying an iPad to use in place of netbook or notebook computer? Since the release of the new Apple slate device a week ago, this question has weighed on the minds of students, parents, teachers and school administrators alike. On the surface, the iPad seems like it could be the ideal device for mobile computing on campus with features like its optional iWork office suite, an Internet-connected bookstore called iBooks which supports the commonly used DRM-free ePub format, the 160,000+ applications available via iTunes, many of which are educational in nature and, of course, access to the greatest research tool ever invented: the Web. However, despite the iPad's pluses, there are still some issues that students should consider before purchasing this device. Sponsor Problem #1: Wi-Fi Access (or Lack Thereof) The iPad comes in several models , each with varying storage sizes and Internet connectivity options. At the bottom of the lineup is the $499 Wi-Fi only 16 GB iPad, the model that money-strapped students can just barely afford, if they can afford an iPad at all. But without a 3G data connection, Internet access may be limited. In fact, students may not even be able to connect to their own college's Wi-Fi network. For example, George Washington University's I.T. Communications and Marketing Manager Rachel Blevins recently told a reporter at the school's independent newspaper that the university's wireless network would not work with the Apple iPad. The problem, explained Blevins, is "both a security and a support issue, because many of the small [personal digital assistants], smartphone, and pad systems use sign-in security, which is currently not compatible with our systems." What Blevins is referring to is the VPN client software currently used at the university to connect students to resources typically limited to campus use only. Although the iPad software has built-in PPTP, IPSec, Cisco VPN software many universities (and of course, businesses too, as we pointed out earlier ) use SSL VPN, a more secure solution which is not supported by the iPad. That means that students with the Wi-Fi only iPad may not be able to connect to their college's network - often the only method of Internet access available in classrooms and other on-campus hangouts. Problem #2: Writing Papers The iPad doesn't come with a keyboard. Although one is available as an optional $69 accessory , the included keyboard on the iPad is a virtual, on-screen keypad. In tests, many iPad reviewers found this keyboard was surprisingly easier to type on than they expected, especially in landscape mode, but for students writing long term papers, it may still fall short. A generation from now, after kids have grown up with touchscreen technology , that may no longer be the case. But at the moment, most college students will likely prefer hardware keyboards. Another issue: when the paper is complete, many professors still require a printout, not an electronic document. However, the iPad doesn't include a printing function. There are a few third-party applications that offer this ability ( WSJ's Walt Mossberg recommends Print Online's $5 app, for example), but none are as simple as a built-in technology would be. (Side note: printing support may be a feature added to the upcoming iPhone/iPad software Apple is announcing later today. Check back for an update). Problem #3 : iWork Doesn't Work for Students? The optional iWork applications (Pages, Sheets and Keynote) are Apple's version of Microsoft Office's Word, Excel and Powerpoint. However, some are already finding them difficult to use for their purposes. One example: in the tests documented here , creating files on the iPad went well, but the sync solution provided by iTunes caused issues for the reviewer. We also noticed some problems ourselves, documented in an early review by Frederic Lardinois: "While you can easily import and export documents (Pages and Word) by email or through iTunes , complex documents don't always survive this move intact," Lardinois explained. "Footnotes and endnotes, for example, are simply deleted, making Pages for the iPad almost useless for a lot of students and academics. Tables of content simply become part of the text, which means that they don't auto-update any more." He also noted that Pages on the iPad doesn't offer a word count, something many college students need in order to know if their paper meets a professor's requirements. Finally, Apple's document-sharing service iWork.com , while great for sharing files with other people, doesn't function as a way to sync files between devices. Problem #4: No USB Port iPad's lack of a USB port may not be an issue for some - so much of what we do now is web-based, after all. However, for college students who have become accustomed to porting their files around on keychain drives, the missing USB port requires a change in their workflow which may not fit in with their current lifestyle. Instead of being able to plug in a portable flash drive to the iPad as they could with their Mac or PC, files can only be sent to the iPad via iTunes sync, email or web download. There are some third-party applications that can help, but again, nothing is as good as a built-in solution. Conclusion: iPad's a Great "In-Between" Device, But Not a Notebook Replacement Despite these disadvantages, the iPad still has a lot to offer college students as an additional device, if not a PC replacement. For example, Blackboard's free iPad application looks quite useful. From the app, students can check grades and assignments, add discussion board comments and blog posts and email instructors and classmates. Plus, the iTunes Application Store has thousands of educational applications like advanced calculators, reference guides, dictionaries, note-taking apps, planners, utilities and much more. The iPad also plays podcasts, like those offered via iTunesU , the collection of audio and video presentations created by many universities to distribute recorded lectures, films, schedules, syllabi, notes, maps and other information to students. However, given the issues listed above, it's clear that the iPad and its software - at least in its current form - is not able to fully replace a notebook computer. Some of the problems may be addressed in time with revisions to the device's software, but for now the device remains a great "in-between" mobile gadget, not a next-gen notebook computer. Discuss

You're looking at what might be the first published cartoon created on an iPad. (Certainly the first one published on ReadWriteWeb.) From the moment rumours about an Apple tablet got serious, I was eager to learn whether it could be a vehicle for actual cartooning. Much of the buzz wasn't promising, suggesting the device would be geared more to consumers than content creators. Sponsor Yet even a device as small as the iPhone has shown remarkable potential with the advent of software like Brushes , which produced artwork good enough - admittedly, thanks to a very talented artist - to become a New Yorker cover . So when Steve Jobs made his Jan. 27 announcement, I was hoping against hope to hear that the device might be a worthy competitor to my beloved (but heavy and unwieldy) Cintiq . In retrospect, that was wildly unrealistic, but I was still disappointed not to hear words like "pressure-sensitive" or "stylus". Yesterday, thanks to the heroic early-morning efforts of my wife , I got my hands on an iPad of my own. And after seeing what my daughter did with Doodle Buddy, I quickly installed Brushes and Autodesk's SketchBook Pro - two drawing apps for nominal grown-ups. After a little experimentation, I landed on SketchBook as my tool of choice for my first experimental cartoon. Still, I had a problem: my big ol' meaty index finger, which is not only a terribly imprecise drawing tool but also a very effective obstacle to seeing just what it is I'm drawing. I quickly found myself hankering for the fine-grained control of my Cintiq's stylus. That was when I remembered the Pogo Sketch ... and discovered it was sold at the same Apple store that sold us our iPads. The Sketch is a slender stylus ending, not in a thin nylon tip like a Wacom stylus, but a soft kind-of-rubbery material that does the same capacitive magic as your finger. And in conjunction with SketchBook Pro, it seemed to mimic pressure-sensitivity. (That's important to many cartoonists, who like the dynamic feel of a line that changes width as they draw.) Most important, it allowed a degree of precision and control I just can't get with my finger, and it allowed me to draw the cartoon you see here. I can't say it's the same quality as cartoons I draw on the Cintiq or with pen and ink... but it's infinitely better than anything I'd achieved on the iPhone. And to me, at least, it holds the promise - as I get a little more practice - of becoming a truly portable sketching, inking and coloring solution. I can see it coming in handy for liveblogging, rough sketches or, on the road, an alternative to more desperate measures . How about you - if you're planning on getting an iPad, will you be using it mainly to read, view and hear content, or will it be a creative outlet, too? And if so, what are you going to make? More Noise to Signal. Discuss

What are the security issues with the iPad and how is it suited as a device for developing enterprise scale applications? Those are the questions we posed to Ken Westin, the founder and CEO of ActiveTrak . Westin is a a security expert. His company develops a software and a service to track the location of a device if lost or stolen. In June, the company is introducing an enterprise version of its technology that will also go by the name ActiveTrak. Sponsor The iPad will become a device that we will undoubtedly see in the enterprise. It fits into the same space as a smartphone or social computing technology, applicable to personal and work life. Neville Hobson on the NextWeb cites a survey by Sybase about the interest in smart phones for the workplace and its correlation to the iPad. But Westin says the iPad does have its own set of limitations that makes it an issue for development of enterprise security grade applications: The iPhone and iPad software has built-in PPTP, IPSec, Cisco VPN software . But more companies are moving to SSL VPN, which is not supported by the iPad. In time, though, a client should be developed for the product. The device may be able to access the domain, however it is different from being a domain member as an administrator cannot manage it, enforce group policies or push patches or apps to it. Westin is supported by other security experts who cite Apple's lack of interest in security issues: "The general consensus is that Apple continues to do only the absolute minimum to address enterprise security and supportability requirements," noted Andrew Storms, Director of Security Operations for nCircle. `We haven't seen any new enterprise iPhone security features from Apple since the summer of 2009 when they introduced their new hardware level encryption, which was almost immediately subverted. This is not the kind of behavior security professionals want to see in vendors.' Recent events seem to illustrate that point. Security researches were able to compromise a fully-updated iPhone 3GS at the recent CanSecWest Pwn2Own competition. Storms warned me "If the iPad has the same OS as the iPhone then enterprises are going to be even more concerned about the data on this device.' " Westin said it is the background processing in particular that makes the iPad less appealing for ActiveTrak. For instance, its application runs in the background on an Android device. An iPad, and for that matter an iPhone, does not provide that capability. His company does provide a free application for the iPhone. It's free but it can only be activated if someone turns it on. To maneuver around the issue, Westin said they disguise the app button as a Safari icon, which activates the application. That's when the tracking starts by triangulation techniques using WiFi and GPS. Westin is a fan of Apple. He uses a MacBook Pro. He says developer tools are better on the iPhone and it has a great community. But, Apple wants it all. It controls the hardware, the software and the content. That's a concern for the enterprise that wants to adopt the iPad. Such control over content is a problem as it gives Apple the power to wipe an application off a device without permission. That may seem unlikely in an enterprise setting but the possibility does lead to hesitation. Further, Apple may make great high end products for consumers but it does not have the equivalent of a Blackberry server that can control the device and its content. Instead, the individual must have a MobileMe account. This can become a coordination nightmare for IT if the enterprise has 5,000 people who need an iPad. Westin said ActiveTrak will wait until the iPad platfrom opens up more before developing. Discuss
