Those of you lucky enough to still be on 2.0.0 or the 01.45.00 baseband will be able to unlock first.

If you are at 2.1 or used PwnageTool to update to 2.2 then you will have the 2.11.07 baseband. This will be the second baseband to receive an unlock.

Those on the 02.28.00 baseband will likely have to wait a while before an unlock is released
