Out of the blue this week, my 8900 goes to GSM for most of the day. I talk to Tmobile Tech support last week, and did everything they told me to do, even thou I told them I already did:
battery pull
host routing table
manually choose network
They tell me they dont know what the problem is, and that I have to talk to someone at RIM and it could take 72 hours for them to get back to me.. Well its been longer then 72 hours..
This exact same thing happened to me last year, around this same time. I complained about it and they sent me a new (referbrished) phone..
Its hard to say. Only things I could see it being is your OS and or the TMO network. If I were you I'd reload the OS to see if its that and if it isn't then I'd see if you can get a replacement assuming there isn't anything wrong with the network
Good luck though.
