That was exactly what I wanted to achieve: My "phone as a phone" needs are low enough to actually experiment with a pure data plan. I did that with Tmo and where it's 3G, it really is blazingly fast and capable of sustaining a full data (voip) call. But try driving and talking (in the passenger seat of course) and it's pretty useless because of the range constantly fluctuating.

Also: State parks = no 3g range. Beach = no 3g range. So pretty much home and a little bit around office = 3g. Is it worth it? Wasn't for me.
Of course, I couldn't go without Internet on my geek device, so I shelled out for an unlimited web + text and limited minutes family plan without a contract. Costs me about $110/month.

I've done this same evaluation on the TMo G2 Android and the Nokia C7. Pretty much same problem. Yes SIP works, but it has the same problems.
On the C7: The default SIP is moody. When it works it is good, but the C7's wifi interface is horrendous. Fring makes it slightly bearable.
On the G2: sipdroid is good and clean in its interface, but comparing to the phone's call quality, falls short by quite a bit.

I'm testing all this on the n950 and I'll post results once I test a little more vigorously.

Cool man. I appreciate the dialog. Often times on here people just put their 2 cents in and then disappear. I am only using the N900, its been my only phone for a loooong time, I had an N95 8GB before, and I don't really plan on purchasing a new one anytime soon either, just too much money to constantly be in flux as far as "geek devices" go

Hearing exactly how different devices perform is interesting at least.
