Hi there, A month or so ago, I bought an iPhone 4S which had an issue where the SIM card wouldn't read sometimes. When I received the phone, it would not read the SIM card at all. I went down to a repair shop recently and got them to replace the SIM card reader. They got it to read for about 30 seconds and then they declared it as ****ed. If it's not the SIM card reader, what could it be? EDIT: I can't use the phone as an iPod either as it's stuck on the activation screen.
