Hi, My apartment has really terrible cell phone signal- to the point that for anyone to hear me I have to walk to the window every single time I get a phone call. My wi-fi, on the other hand, is great, (just got a new Time Capsule to dispense my speedy 34 Mbps cable connection ). I would like to know if anyone has a suggestion for a good Voice Over IP app for the iPhone- ideally one that used my current phone number, but even that is not a prerequisite. I've tried Google Voice with mixed results. Any opinions or ideas?
