The iPhone Dev-Team has announced the UltraSn0w unlock for iPhones running the 3.0 firmware.

The UltraSn0w unlock will be released on Friday and will be applied in the same manner as the previous yellowsn0w unlock. The procedure will work on the 4.26.08 baseband version so all those who accidentally updated to the latest baseband will be able to regain their unlock.

Once the iPhone Dev-Team has made the tools available we will be posting a detailed tutorial with clear instructions on how to apply it
