One of the many features that's available on Mac OS X, but not on iOS yet, is the ability to have multiple user accounts on a single mobile device. iUsers is a tweak for the iPad from Cydia, which means, yes, your iPad will have to be jailbroken in order to access it. It seperates application information and preferences between users. This means that one user's Angry Birds score will not affect another user's game, even though they're using the same device to play.
Your iPad can be used by different users
Currently, apps, music and videos are shared between users but the developers of iUsers hope to fix that in the near future. The tweak should be available in Cydia soon, but those that want a sneak preview, follow the instructions on how to here. Do you share your iPad with various users? Would you like to be able to create multiple user accounts? Let us know in the comments section below.
