I am a gadget geek and just received my new N1 and I am impressed with the phone overall. I already have an Iphone 3GS , Palm pre with service and did not want to start a third new service with tmobile with data. Hence got the phone unlocked at $530 and put in a tmobile prepaid SIm card. My plan was to use google voice for the calls since I am in wifi zone most of the time. After setting up GV and placing a couple of calls I realised that I am still loosing my cell phone minutes. Is this true or am I missing some configuration. Pardon my ignorance if this is a silly question but what is the point of using GV for US domestic call ( I can understand international calls for cheap rates) if I will loose cell minutes? Isn't it the same as placing a call directly? Am I missing something?
