I'm from Moldova, my carrier MD moldcell, Ibought the iphone in canada. I don't get any errors it's just always show searching for network, after I've changed the sim a few times it show no service.

P.S. iPhone 3gs 32gb black

thx I'll try this and I made a backup of my latest version and I can.t go back to it..

now I can't acyivated it

I lost all the day out trying to fix it

and now I don't have even an Ipod

there is no message]\

it say's try again

this is not a message]

and i think that here the guys from apple must change a little the itunes, to give the last updates of the firmwares that work with the iphone you use beacause I thijnk that this firmware it's not so good for 3gs

it says that the activation server is not available try to conect to itunes to activete it, I've connected the phone and in Itunes was written that there is no sim card on iphone , I have tryed to insert it o few times and there was no result

thx for "support" i did it by my self nad in the future I'll never use the help of apple
