It has bluetooth. However, according to what I read so far, many bluetooth prepaid phone doesn't offer DUN via bluetooth.

Does anybody know whether this particular phone can do bluetooth DUN with N800?

I just called Tmobile, who tells me it does support bluetooth dial-up networking with computer. The speed is slow though, only 32-48 Kilobits per second.

What they didn't mention is that you won't actually be able to get online with it with a prepaid phone. There isn't a way to add the data service to my knowledge to a prepaid phone. This may have changed since I looked last. I would call TMO again and ask them if you are charged a per day data rate for tethering.. Just to save yourself some headache.

Boost is a prepaid service that allows data service (thru iDEN network), and it's free as long as you add $20 for your minutes every 90 days. I am currently on vacation, and have been using it exclusively for three days (even now). It is not as slow as I imagined it to be.
