        I have synch my I phone 4 to my laptop, creating a recovery point for my Phone. When, i tried to do a recovery for the iphone 3g on my laptop, it installed the iphone 4’s recovery point.Now it keeps telling me that my sim card is invalid.

        Is there a way how to reinstall the 3g software? Basically get it as it was when originally bought?

        Thanks for your support and help.

            You must upgrade your current firmware to iOS 4.1 or iOS 4.2.1 and then upgrade its baseband to iPad baseband http://bit.ly/gI22Px This might lose you GPS functionality but it will unlock your iPhone. Ultrasn0w 1.2.3 can not unlock iPhone 3G bb 05.15.04 directly.
