Additional info - it looks like some people (depending from TMo plan) may need setup additional GPRS connection (via fAPN) with proxy server 216.155.165.50, port 8080 (or 9201 - different sources point to different ports). Because TMo blocks a direct Internet access for that people. Use the usual wap.voicestream.com as "APN name" in this connection. Please don't mix it with APN in fMMS - that is different items.
