I’m probably the only person with this combination, but to get it online:
0) Downloand suitable drivers from Palm.com
1) Turn on irDA connection on the phone
2) Open WebPro (this will correctly connect to network, opening other network using applications first will give you an error message)
3) WebPro doesn’t seem to work right away, but Avant Go does.
Results: using T-mobile GPRS as the cell phone network, you can get data at about 1KB per second, so http browsing is not practical. Next: testing WAP.
