I recently bought a brand new white iPhone 4 a few days ago from Verizon, and the first thing I did was jailbreak it after I got it. Now for the past few days whenever I wake up, the iphone is frozen ..and the only way I can turn it back on is by resetting it with the home and power buttons. does anyone know how I can fix this? It works fine during the day but for some reason it freezes overnight when I'm asleep. Also if I restore it to try and fix this problem, will the firmware update to the latest one , I'm on 4.2.8 currently and I'd rather leave it at that .
