Please note: only Apple can obtain and use Apple Certified parts. We use parts from only a few trusted U.S. distributors that are excellent quality. They are classified as grade A or better cell phone parts. These parts are manufactured by the same factories that manufacture parts for Apple but are not certified by Apple. Please remember that no independent repair shops can obtain Apple Certified parts and that the term, “Genuine Parts,” does not have anything to do with Apple Certified parts. If you have concerns or questions please contact me before your repair.
