Better GSM Service? AT&T or T-Mobile?? I think T-Mobile is better so far, but will AT&T take the throne within the next year? I had T-Mobile for a year, and now I have AT&T and I liked T-Mobile better... Hopefully AT&T will step up to the plate. T-Mobile has better text messaging packages, even though AT&T has free incoming, T-Mobile is more flexible. The highest text plan with AT&T is currently only 100 outgoing messages and 10 cents a message after 100. That is terrible, especially after the way they plug text messaging. The mMode online stuff is good... Pretty costly, but good. Theirs is better than T-Mobile. I spend more time AT&T's mMode than T-Mobile's T-Zones. AT&T also got T-Mobile beat with features, like 6-Way calling, and the #121 service. They just need to touch up their GSM service, and improve their text messaging... Opinions?
