    I'm using T-mo 8900 with OS 4.6.1.310. I just updated my WLM to the newer version. it used to work, but it is not working now. everytime i try to sign in, there is a box saying "data services unavailable!". the problem is i do have data plan for blackberry. I have uninstalled an reinstalled it 3x, with re-regestering the service book everytime. can anyone help me? thx b4

    i just got my 8900 and had the same issue. i deleted all the service books under advanced options. there is one you cannot delete, just leave that one there, then reboot (alt + shift + del). you should be good to go.
