My sister recently dropped here iPhone 4 which caused the digitizer to crack and the back plate to crack too. my question for you guys (the experts) is where do i get a good digitizer and back plate from? there are so many place to buy from and it seems very confusing. a little info i might add is the phone was originally black but now she wants white which is easy enough. so to sum it up where can i get a White iPhone 4 CDMA Digitizer + White Back Plate + White Home Button from that is good quality but not ridiculously priced ?
