Use Skype to get calls in low coverage areas?
I currently I have pretty poor 3G service in my apartment. I was wondering if it might be possible to use Skype for iPhone in order to forward incoming calls to my ATT phone number and forward them to my Skype phone number (using call forwarding on my iPhone) so that I can talk on Skype over Wifi in my apartment. (I don't need to use Skype on 3G since I have poor 3G service anyway).
Does anyone know how this is done or what the cost is? (I hear there is a fee for calls).
Currently I am having my calls forwarded from my cell phone to my home phone land line, but it's rather expensive to pay for an extra phone line just for the few calls that I receive at home.
