Axim X50v RazrV3t + T-Mobile GPRS

[MatthewH12]

I am trying to link my AximX50v with my RazrV3t so I can use my t-mobile GPRS connection (the $5.99 plan).

Here's my setup:
T-Mobile (Work)
Number: *99#
Username, pass & domain blank
Extra string: +CGDCONT=1,"IP","wap.voicestream.com"

I have tried it both with the proxy: 216.155.165.050:8080, and without.

Both times the PDA + Phone connect, phone dials, the new icon appears right next to my signal bar, along with the BT icon, but PocketIE fails. With the proxy on, it gets stuck at "locating" then fails with: The page could not be displayed or downloaded because the connection was lost (The two devices still show as connected, BT lights blinking & all). If I turn the proxy off, it gets stuck at "Opening", and either fails with: The page could not be displayed or downloaded because the connection was lost; Or: Error 502 bad request
The server could not resolve your request for url: /mobile/pocketpc (I was texting using the Dell link on the main PocketIE Axim page).

Any ideas?

Thanks!
