My iphone 3g is finally back in service. Sort of. A year ago I shattered my iPhone 3g screen and just let it collect dust, while I used my Blackberry Bold. I started to miss my iPhone so, I ordered a full lcd/digitizer assembly for my phone. I installed it and let it charge and voila. Back to Life. However, I noticed a strange issue that Im not sure is related to the screen itself or not. Multiple times a day, the screen will just become unresponsive almost like the phone froze. However, all I have to do is lock and unlock my phone and the screen is back to normal. Not a huge deal, but it gets kind of annoying. Do you think that my new screen is defective or is it a problem with the phone itself?
