Accordian Man, some more information on the Earthlink BlackBerry 7750 is available here:

Based on what I've read, Earthlink uses Verizon's CDMA network, so coverage should be identical. However, I do not know whether Earthlink includes a Web Browser with their service. In addition, if you wanted to use the Earthlink service just for BlackBerry access, you'd be carrying two devices around - one, the Verizon device for voice, and the other, an Earthlink Blackberry.
Wish Verizon would just get with the program and include a browser, or not count against your minutes when using a 3rd party browser.
