My itouch is not reacting to what i tell it to do. When i pressed the unlock button it took like 10 secs to unlock, then when i slid the slider, it took like 10 seconds after i slid it to actually slide. Its all slow, i managed to finally get into settings (defalt app) and it was normal in there. What is wrong. I tried turning on and off. Should i restore and jailbreak agian? any advice?
