    Hey guys,

    I have an iPhone 4 that I am unable to activate. I have placed my valid At&t sim card and i get "SIM not valid - The SIM card inserted in this iPhone does not appear to be supported" even though it works when i put it into my iPhone. I have called at&t and ran the imei number and they said it was clean, not tied to anyone's account. I have tried restoring it to no avail. Anyone have any suggestions?

    Thanks

    some older iphones had SIM card tray errors due to hardware malfunction. my att iphone 4 had the issue and i tried replaceing the SIM card first, but it wouldnt go away. it would read the card, then randomly say "No SIM". my suggestion would be to get a new SIM from att. if that doesnt work, my money is that it is probably the sim card reader.
