Hi all - I've just bought a 3GS and the carrier information is missing. I can't send MMS or use the net, the Cellular Data Network tab is missing from settings, no MMS option from the photos menu (my BIGGEST problem ) etc. I'm on O2- UK I've hooked it up to Tiny Umbrella and lo - all the blobs are there so the supposedly naive chap I got it off obviously restored it from a JB'd state before selling it to me.. What do I do to get my carrier info/cellular data tab back? It's currently on 4.0.2. Help me MacRumours - you're my only hope... Thanks.
