I think it was Retinasizer, as it was the last thing I downloaded from Cydia. The problem is, when I slide to unlock and go to the home screen, nothing is wrong. However, when I try to load up any app, even the stock Apple ones, it displays in the top left corner of the screen. See the link attached for an example of what it looks like (it began acting like this after I rebooted after updating Retinasizer). http://modmyi.com/forums/general-iphone-chat/731232-apps-running-half-resolution-iphone-4-a.html Please help? The only input I can give the phone (aside from any buttons in the top left corner) is through voice control, which lets me make calls/control my iPod and that's it. Is a restore the only way I can fix this?
