    Great and easy instructions to follow but once I finished the jailbreak and unlock, which went fine, my iPhone 3GS recognized the new SIM card and carrier for ONLY a couple SECONDS before SEARCHING and searching for the carrier and stating “unable to load network list” and never recognizing the carrier. Any remedies for this?
    Thanks!
