Same issue after 90 days repair warranty
Late January my phone was repaired by Apple, they changes the Rear system because the back glass was broken. In July my phone couldn't connect to the cellular network. Genius Bar confirmed they replaced the "rear system" ever it changed the serial number, but they will not repair unless I pay us$650. because repair warranty is only 90 days. Should Apple cover the repair since the part they used is failing now? Any idea how I can get help to fix the iPhone?
