Check out Treo 650. Spendy, and the Cingular data plan is a bit too pricey for my blood, but it's an amazing phone. A friend of mine has one and, among other things, streams shoutcast music to it. It's my understanding that the equivalent Sprint plan might be cheaper.
I'm... not sure you understood my post. The Treo 650 is available for both Cingular and Sprint. I am on Cingular, and I consequently passed on the phone because the plan was 'spensive, but as I said at the end, I've heard that Spring (who ALSO offers the phone) has a cheaper data plan, so it might be worth checking out.
And no, it is usually the case that phones can NOT be used on with other carrier. There are exceptions (for instance, you can sometimes buy an unlocked phone that works between two carriers of the same technology, aka T-Mobile and Cingular, but you pay for the privillege).
In your buying criteria, look for a phone that supports Dial-Up-Networking profiles and can be used as a modem. I think Sprint has like a $15 a month unlimited data option that you could use to then have your carputer connect to the internet via your cell phone without costing you an arm and a leg.
If the phone has bluetooth, then the whole process can be transparent too, with no wires.
I'm definatley going to be asking about that. I've been tracking the Sprint Hacking Thread and supossedly they are trying to limit that type access to their PCMIA style cellular modems. I'll see when I ge there.
KAI, what can you tell me about this paln I found on the Sprint site:
