I am looking at acquiring my first Android phone and came across this used Nexus S offering: "The Phone is in great shape and there are no scratches on the screen. The phone comes with a case, screen cleaner, charger, and original box plus manual. Reason I am selling the phone is because my friend tried to root the phone, and now it doesn't connect to WiFi anymore. It seem to be a software problem(easily fixable). Everything else in the phone works fine it can still connect to 3G make phone calls go on the internet." Does this device sound fixable? Since it is a Google phone and turns on, can I connect it to PC and download/install updates directly from Google to make it stock again? Or should I avoid this device altogether? I do not know what ROM was installed. Thanks in advance!
