I was having some problems with ATT so I recently went in and discussed the issue with an official in a nearby ATT Store! He asked me for the device so I gave it to him... he went inside somewhere! When he came back, my problem was solved but my iPhone's chrome logo was brutally scratched....
So I've decided that I'll be taking it in after all and get a replacement!
Oh I almost had the same problem. I went to T-Mobile (I live in the Netherlands) about the Speedmanager that is really annoying... anyway, they wanted to see my phone and the sales man had these huge rings on (his fingers), and I was sure he was going to scratch it. But it looks OK.
