Hello, Total newbie to the 'smartphone' arena, so please excuse me if my question(s) seem very basic. Short history - traded a very old Fujitsu notebook for the Huawei Ascend. Do not have a carrier(it is a Metro phone) and do not get cell service where I am(radio quiet zone). I am assuming this phone has not been rooted or even 100% sure what that means or entails. Objective - is to use available wi-fi to make and receive calls. I have tried uploading Talkatone, but to no avail. I do have an active Gmail account with voice and talk. According to the information on the phone itself, I have Android OS version 2.2.2 Anyway to get Talkatone up and running on this thing, or another 'free' app that would work? If not, what paid app would you suggest? Any and all help would be appreciated!
