Anybody have one? I'm thinking of switching back to Verizon and getting one to use for work. Email and unlimited webtime with 1350 anytime cell minutes for $109 a month. I have to look into Sprint/Nextel's plans too although Nextel only has Blackberry phones which I've heard mixed things on with regrad to web stuff. I don't think that Cingular carries them but I have to look more into that too. Anybody use one? What is a good unit?
