Ok so i have my Iphone and it keeps giving me the same old error: Needs Repair Cannot call or recieve calls. And when i tried to go on wifi it just says no wifi in settings. I have version 1.1.4 and i dont know what was used to unlock the phone as i bought it off a guy from craigslist. Im wondering if i should restore it and try to re unlock it using Ziphone. When i talked to the guy that sold it to me he told me to not update it as it will ruin the phone what exactly should i do?
