Surprise, Surprise! The iPhone 3G 2.2 unlocked!
Looks like the Dev Team delivered much more than it originally promised us in 2008. The team originally planned on releasing a SIM unlock for version 2.1 of the firmware which included an older version of the baseband, but after some last minute work they ended up releasing an unlock which works with the latest firmware 2.2 baseband, version 2.28.
