Any way to use the Droid to make calls over WiFi as opposed to the VZW network? I have terrible coverage at my house, and would like to just use my WiFi connection. I would need to be able to go over WiFi but still be considered a Verizon Wireless call, as I call a lot of people with Verizon and take advantage of the free calling to Verizon customers. I don't see why Verizon wouldn't take advantage of something like this, it would only take strain off of their network if some users are connecting on their WiFi networks.
