I know I have a thread about this already, but decided my original post was not specific enough. The background, I have a friend who currently has a 3G. She is being given a 3GS. The 3GS has a cracked screen. LCD if fine. So, she wants to swap the glass/digitizer assembly between units. As I understand it, the LCD cable is different between the 3G and 3GS models. Is this the only difference? Meaning specifically, can I take her iPhone apart, remove the LCD from the screen assembly, then swap the glass/digitizer between the two units? The LCDs will remain with their original unit. Will this work? Thanks for info!
