I am Dallas and i am having this problem today too. It is weird i never experienced this in my entire life with T-mobile (4yrs) However i did happen to talk to a T-mobile rep and he said that his network was down too. I mean the T-mobile account network to see minutes,add lines and activate new accounts. He said they where updating something in the system and 'maybe' we could be getting some of the problems. He also mentioned that there HSPA is getting updated later this year to higher speeds equal to 4G.
