Here’s a really cool new Cydia hack: iUsers, a jailbreak add on that allows you to have multiple user accounts on a single iPad, each with their own separate apps, mailboxes and settings.
iUsers is designed by Pedro Franceschi, who previously designed PhySwitch, a Cydia app that allowed you to switch between apps using your volume controls.
As you can see, iUsers seems to work pretty well. The only thing that really seems like a problem is that the iPad seems to need to reboot itself every time you switch users. That’s hardly seamless.
If you’d like to try iUsers for yourself, just add http://cydia.iblogeek.com/ as a source in Cydia and search for iUsers.
