Antwoord op "iPod 4th gen does not power up after screen repalcement"I think I know the answer to your problem from my experience of replacing ipods: make sure that you have not damaged the logic board of the iPod because if you did you would have to replace that too. Also make sure that the LCD is properly connected to the logic board and that the black square that connects it is not damaged Hope this helped
Antwoord op "iPhone 4S Rear Glass Panel Compatability"There is no one answer to your question but from the experience and knowledge i have from fixing every type of apple product, the back panel of the all iPhone 4s are the same, but i wouldn't take the chance because the antenna might be there so to be on the safe side use the CDMA iPhone 4s rear assembly
