Ok, so I was having all sorts of problems with WLM. It would sign on for about 2 hrs, then sign off for 2 hrs and give me all sorts of connection errors (65, 66, can't connect to server...), then repeat. I called T-Mobile, who linked me to BlackBerry, who determined that it was the missing "Windows Live [BBIMConfig]" service book that somehow was not getting pushed to my phone during normal "power cycles (battery pulls)".
Weird, but when BlackBerry remotely resent my service books, I got the BBIMConfig service book came up. Smooth sailing. Ever since. Sorry, can't really see what I am typing because BBF wap won't show any characters I'm typing after about ten lines. The mods should be notified. Anyway, solution: call BlackBerry and have them resend your service bboks, or call TMo. And have them link you to BlackBerry.
