If you have ever wanted the iPad to be more like a PC with it’s multitasking, then this tweak may be for you. You can move windows around and have multiple apps viewable at once.
Quasar from Cydia allows you to have multiple windows open at one time. You can watch a video on one part of your screen and browse the web on another part of your screen like you would on a PC or Mac.
This works with the new 5.1.1 untethered Jailbreak on the iPad 1,2 and the new iPad (iPad 3).
Quasar – BigBoss Repo – $9.99 /£6.99
