My bumper (ordered from Apple, using the iPhone app) has damaged my iPhone 4 significantly by leaving scratch marks all around the aluminum rim!! Despite only having the bumper for 2 weeks, and the iPhone for 3 weeks, upon removing my bumper I noticed that there are scratch marks in clusters all around the aluminum strip on the side of the phone. They look like bite marks in a way and it REALLY sucks that an Apple-produced accessory could damage an Apple product in such a way! I took it in to the Santa Monica store and after much debate regarding a couple of associates and one of the store managers they eventually agreed that they would replace my device. I still had to back it up though but they told me that this was a ONCE TIME EXCEPTION and the damage counts as user-inflicted damage, thus exempting the damage from the warranty. What does everyone think regarding this? Has anyone else had similar issues? Btw, I'm a new member to this forum (although I have been using the site for many years- it's my home page!!) so hello everyone now that I've joined!!
