i have always found 5.1.1 being the most stable iOS for my iPad2, but recent app updates have been ceased because they require iOS 6 at least. The problem is now that I have lost my stock backup before the jailbreak of my 5.1.1 and I read that direct update to 6x is impossible because it may brick my iPad. Also, OTA Update will bring me directly to iOS 7. anybody knows the solution to this? I am fine with either iOS 6 or 7, whichever is most performance and battery friendly, but I want it to be jailbroken again after the update. thanks beforehand.
