Don't bother with the NWeb browser, that's all it is is a mobile browser. Bluetooth is also not useful, because it doesn't maintain a persistent connection of that type.
Your best bet would be to use your data transfer cable to dial out to a dial-up isp. Otherwise you would have to have a WinMo phone and use the internet sharing, which is actually what I do with my
HTC PPC6800. Just keep in mind that USCC has a 5 Gig/mo data cap.
