TROLLTECH Greenphone (Powered By Linux)

This is one of the phones I have considered trying with my data plan enabled VoIP (SIP) phones system that I am building. My problem is I can get cheaper plans on evdo as I get a discount due to that is what my business phone is from my company.

It looks like a nice phone and is the front runner if I can not find one to work with evdo.

I may have overlooked this bit of information, but do you happen to know which carriers will provide service for this phone? It looks pretty interesting.
