With Cingular look at the Nokia E62, I have the E61 here in Australia.
Difference in the two being the E61 has WIFI the E62 doesn't.
Seems Cingular is worried people in the US will use it to make VOIP calls and cut them out if they include WIFI with it since it comes preloaded with the software for VOIP calls.
Mine has been very very reliable, battery time is fantastic and it takes a ton of abuse. Every kind of email client you could want is pre set up in it, web browsing, ssh, IM etc.. on it all work flawless.
