Well I do have an Audiovox 5600 on ATT. I haven't had any reason to switch to Cingular so I haven't. Plus, I'm not sure if Cingular will officially support my phone. But maybe it's worth doing so now. It's too bad they only have the 600 and not the 650. Do you know if their Blackberry phone can be used as a generic data device without the special Blackberry service?

TMobile gets no coverage at all at my house. TMobile won't even let me initiate service from my zip code and friend's phones get no service.
