Applications like iUser are why I love the Jailbreak community. The iPad is a decidely less personal device than the iPhone. A phone is an individual's personal property and often times contains embarrassing information on it. You wouldn't expect a family member or friend to use your phone without permission, and rifle through your emails, text messages and other information.
The iPad? Not so much. While it may stand that a household could have a couple iPads bought by one person or another, in many homes the device sees the hands of many users. It's a coffee table companion. iUser allows the iPad to have multiple iOS user accounts just like users can on their Macs. This allows multiple users in the same household to customize one iPad any way they see fit.
The iUser hack for Jailbroken iPads, developed by Pedro Fransceschi, lets users sign in using accounts and passwords. Once signed in the user is greeted with all their own customized settings including apps, wallpapers, and just about anything else. The only caveat is backing up your iPad with iTunes. As iDownloadBlog points out, this could create some potential problems for users.
I have not restored my iPad 2 from a backup with this particular tweak yet, but I'll let everyone know as soon as I create multiple accounts with wildly different settings. In the meantime if anyone has experience with the Tweak, and how iTunes plays with it let us know in the comments.
iUsers is available in the cydia.ibloggeek.com repository. It is another perfect example of how the Jailbreak community is picking up the slack Apple feels the need to leave behind.
