i have two iphone 3g that id like to replace the back housings on. I repair iphones so actually doin it is not a problem. What im having trouble with is finding good OEM or close aftermarket parts. when installing flex cable, i have trouble installing the vibrate button and getting it to click rather than slide back and forth. When i put flex cable from an original iphone 3g housing to another original housing, i can get the vibrate button to work perfect....Any good places to get OEM back housings that dont charge an arm or a leg? or anyone know of a good ebayer? any help is appreciated.
