Okay....I bought a bricked iphone 3gs 16gig and I have managed to restore it to ios 4.1 with 6.15 baseband. I have unlocked and installed ultrasnow to unlock. The phone is showing the carrier when the sim is installed (Vodaphone uk) but whatever I do I cant seem to get any service. Have tried sim in/out and Airoplane mode off/on but still no joy. Have also tried Orange sim and still the same. Anyone have a solution for this please?
