I'm sure others have had this problem, but ever since iOS 7, my iPad 2 has lagged. I've done updates due to all the promises of "fixes", but it still lags...even 8.1.1 which was released to specifically address the issue. I've restored and it doesn't fix anything.
Any way with the current jailbreak to downgrade all the way to 6.1.3?
