I jailbroke/unlocked 2.0.1 with Winpwn awhile ago and everything was working fine. Now my phone has been lagging (ie. over 20 seconds to open text messages, camera never loads and when it does there are bars all over the screen.) Safari always crashes, and when it does my entire phone freezes. Non of my apps work either, if I click on monkey ball the screen just turns black and my phone resets. I have no idea whats going on...any help?
