Has anyone tried using a wifi enabled pocket pc like a Dell Axim, HP ipaq, or a Treo as a cell phone thru VOIP? You can use vonage for your home, and its softphone on your pocket pc. Or use Verizon's wireless broadband data, but not their phone network. I have been paying for both wireless data and phone service for almost 3 years now, but the phone service fee seems kinda redundant now with voip and wifi. I am thinking about no longer paying for wireless phone service, just data?
