Apart from the Chronic Dev Team, MuscleNerd was also there to deliver a presentation on "Evolution of iPhone Basebadns and Unlocks," today, the video of it has been uploaded on YouTube.
He shows the complexity involved in unlocking an iPhone baseband, the techniques he used, and how Apple has tried to counter iPhone unlocking. The slides of his presentation are also available for those who understand the technical side of the video.

Evolution of iPhone Basebad Unlock
He also mentioned the downgrading solution for 06.15.00 baseband was far off when he gave the presentation. It is going to release sometime today, because he was able to do it faster than he anticipated. You should also know that 4.11.08 was unlocked by the SAM unlock tool on iOS 5.1.1 but was short lived and patched by Apple.
Those who saved activation tickets were still able to keep the unlock. Other hardware solutions like Gevey SIM, R-SIM 4 and Rebel Pro Micro SIM copied the SAM unlock and didn’t work after its end. As off now, there is no unlock solution for 4.12.01 / 4.11.08 baseband on iOS 5.1.1 for iPhone 4.

Those who unlocked via SAM unlock tool shouldn’t update to iOS 6 as MuscleNerd jailbroke his iPod Touch 4G on iOS 6 but said it had many complication and would be long before untethered jailbreak is release which is the breeding ground for SAM unlock. Ultrasn0w tool will be updated in the future and the current version 1.2.7 only locks older basebands for iPhone 4 and 3GS.
Confirmation has still to arrive from ApplenBerry whether it will be safe to update to the latest firmware when it gets released publically.
