Can the iPad 3G receive phone calls just like a regular phone? If it can, then I am thinking about getting rid of my phone and just use the iPad for calling and text. I barely use the phone/voice service, maybe 10 calls a week just about. 2 major questions: I know that I am able to make calls using skype and similiar apps. How is the voice quality with verizon/AT&T 3G service? Do you think it's good enough to replace my phone? If someone calls me, will my ipad ring or get a push notification? Please give me some advice.
