Over the past week the dev team has made some good progress towards 3g unlocking.
The above screenshot and this video are of a 3g iPhone with a modified baseband. The news is that although the baseband fails integrity checks it is still running! So now the dev team can run a modified baseband on the 3g iPhone.
While the dev team still can not estimate how far they are away from a 3g software unlock this is a step in the right direction.
