I'll chime in.

I'm on year three for the same iPhone and it has out lasted two different company phones (motorola and samsung) over the same period. I do use an incase slider case which has finally been replaced since the old one was looking pretty bad after 2 years of hard wear, lots of scrapes and the occasion 2'-3' drop onto unforgiving surfaces. Still not sure how I have avoided breaking the glass - maybe just lucky?

Anyway it has been a tough reliable phone and has never been back to AT&T or Apple for any reason. Phone is not jail broken but has lots of apps on it. I even played with the developers kit for a while.
