As we All Know or maybe the most of Us know that Apple Released iOS 4.2.1 and Many people will try to check it out but after that they may CRY if there iOS devices are NOT Unlockable So here is MUST read INFO:

THIS INFO BY DEV-TEAM:

1- ultrasn0w unlockers please stay far far away from this official firmware (and all official firmware). Wait for the ability to create custom 4.2.1. IPSWs that don’t update your baseband.

2- owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G. Due to a combination of our original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is “just as jailbreakable as ever.” You reap the full benefit of an untethered 4.2.1 jailbreak.

3- the owners of all the more recent devices. The good news there is that due to geohot’s limera1n exploit, all recent devices can be jailbroken (this will be true until Apple released new hardware that fixes geohot’s limerain exploit in the bootrom). The bad news is that right now, the 4.2.1 jailbreak is *tethered* on all of these recent devices. A tethered jailbreak means that each time your device loses battery power or needs to be rebooted, you must attach it to a PC or Mac to boot into the jailbroken state.

4- if you’re a JB developer or tinkerer, you Can probably use the redsn0w0.9.6B3 to jailbreak 4.2.1 and at least get SSH working.

5- please make sure you have your 4.1 SHSH blobs for all your devices ( By TinyUmbrella ). These will be important even for firmware beyond 4.1 (using both comex’s method and our alternative, depending on how each of them turn out.)
