Hi All - I have a quick 3G question. Is the benefit to 3G data only or does the quality of the iPhone calling increase as well? For example, at my house I generally get very low signal strength on my phone. Will 3G help me go from 1 bar to 3 bars? I'm not asking for that specific of a range in signal strength but I am asking if the signal strength is likely to be stronger on a 3G network in areas that may have lower signal strength using the Edge network iPhone. Thanks, Everyone for responses.
