Another Blackberry option
Earthlink has for years been buying Blackberry time and packaging it and selling it as their own branded service. This includes customer support directly from Earthlink which I have used on a couple of occassions and been very pleased with. Up until recently they were reselling the Cingular Mobitex service but they have now added (part of a phased transition I would imagine) what appears to be Verizon 1x CDMA Blackberrys to their marketing. From what I see on their web pages they are selling this for $10 less per month than Verizon is selling it for. If you are in the market for a US only Blackberry it might be worth a look.
