my 12 year old son has an iPhone 4s that he mainly uses as an ipod to play games etc. He can use free text/call apps when at home for wifi, but he does not have service on the phone. That being said, he has been bugging me everyday for a while now to upgrade it to iOS6. I guess there are some cool updates that he wants that he doesnt have? That being said, i looked online and couldnt find any clear cut answers. is this possible to do it untethered? if so, is it as simple as redsnow or something? please help, thanks!
