So heres the story. Few months back. Horrible Accident. Iphone 3Gs fell out of car whilst getting out. *Crack*. Yadda Yadda. OCD In me hates cracks, and it felt 'trashy' to use; so it sits in a drawer whilst I use my 3G. However I miss the processing speed so much. as well as some IOS4 Capabilities. Is it possible just to switch the glass plates? Or am I wasting my time if I try?
