I was with Att before it became Cingular, and stayed with them through the transition back to being called Att. I lost plan features (device replacement insurance, competitive sms rates, etc.) and suffered rate increases both times the company restructured. My company offers iPhones, so I really only keep a non-business cell for sms and an occasional call. So far, T-mobile has been great for that (in Houston), and I am confident my monthly price would increase - perhaps even double - under Att.
