Hi, I've been messing around with my 3GS FW 4.3.1 BB 06.15.00 and can't manage to get it unlocked using ultrasnow. My carrier does say 'O2 10.0' but the network says 'not available'. It appears that tue unlock may have worked but something is still wrong. Does anyone have the same problem? I was just thinking that it may be that my aerial isn't working and it may need re-connecting or fixing. Any suggestions?
