I've had my white 3G less than a month. This morning I was cleaning it with some iKlear and half of the silver Apple logo on the back peeled off Has this happened to anyone else? I've never used a case and only clean it with iKlear and the micro fiber cloth supplied with the iKlear. Should I try to exchange the iphone? It's been under 30 days since I bought it. Seems like shoddy workmanship to me having this happen on a brand new phone.
