Left ATT a long time ago because it was expensive and they had horrible service. Have been with Voicestream, which became T-mobile, since about 1998 or 1999. Have had a great voice, text, and data plan for years with t-mobile, with very good coverage and very good customer service. Also had my choice of great unlocked phones for all these years (including my N900). Heard ATT has sucked ever since I left and through their Cingular years. I hope every T-mobile customer jumps ship after the transition and ATT goes broke. Especially after hearing the other day that ATT is trying to strong arm customers who tether by automatically ugrading their contracts.
