@MuscleNerd, an integral member of the Dev Team, tweeted today that along with an iPhone 4 unlock, an unlock might also be possible for the 3G and the 3GS on some of the newer basebands.
Judging from the tweets listed above, it looks like the rumors are true, and that we can expect an unlock on the horizon any day now for iPhone 4′s running basebands 3.10.01 or 2.10.04. They are even working on an unlock for 04.10.01 basebands for 4.3b3 firmware.
As you’ve probably heard, the unlock will likely come after the release of iOS 4.3, as @MuscleNerd stated earlier in the year.
It’s getting closer and closer to reality folks, all of you with iPhone 4 paper weights will soon be able to rejoice!
Are you pumped, or what?
