Beware iPhone Unlockers: Apple iOs 4.2.1 Has A Baseband Requirements

It looks like the iPhone maker Apple has secretly imbedded “baseband requirements” traps on the freshly released iOS 4.2.1 operating system for iPhone jailbreakers and especially to iPhone unlockers. As reported by Semaphore, the developer of the popular TinyUmbrella program:
"It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainer. Do not update to 4.2.1 even to test it at this point."
Meaning, if you utilized Saurik’s server or the TinyUmbrella software to restore iOS 4.2.1 on an iPhone without upgrading your baseband, you will end up in recovery mode and TinyUmbrella has no capability to pull you out of recovery. So, the best thing to do for all iPhone unlockers out there is to STAY AWAY from Redsn0w 0.9.6b4, the first jailbreak tool developed by iPhone Dev Team that jailbreaks the iOS 4.2.1, and from the iOS 4.2.12 firmware. Do not even tempt to test it o it will lose your ability to unlock your iPhone.

So are you saying that it is now possible to unlock a 3GS with 4.1 on it?
Or as in my case, unlock a 3GS with 4.0 and BB 05.14.02? (which I'm stuck with after downgrading from an unfortunate mistake earlier this fall where I upgraded from 3.2 something)
Unlock for iPhone 3G for all firmware versions released.
Just install firmware via iTunes and download ultrasn0w from cydia to unlock it!
iPhone 3G 4.2.1 custom firmware with baseband 6.15 for unlock:
