Unlock Baseband 04.12.01 Method

If you are looking to unlock baseband 04.12.01 there are some bitter news for you. A week ago Apple released the newest version of iOS – 5.1 to the public. The hackers society already warned everyone who would like to jailbreak or unlock on that iOS to stay away from it and stick to safe iOS 5.0.1 untethered jailbreak. Those iPad 2 and iPhone 4S owners who want to save their jailbreaks should beware of iOS 5.1 because there’s no way to downgrade from iOS 5.1 to iOS 5.0.1 or iOS 5.0 even in case if you have your SHSH blobs saved. The reason is simple – Apple company stopped signing older firmwares on pointed devices.

The new iOS 5.1 firmware brings baseband update to iPhone 4 and iPhone 4S in the same way as iOS 5.0 did. That’s why if you are an iPhone 4 or iPhone 4S owner and you updated your iPhone to iOS 5.1 there is some bad news for you. iPhone 4 will get baseband 4.12.01 and iPhone 4S – baseband 2.0.10 respectively. Right now there’s neither unlocking nor jailbreaking solutions for any of those basebands.

There are lots of unlucky user who accidently upgraded their iPhone 4 or iPhone 4S to the latest iOS 5.1 firmware without being aware that it will disable both unlock and jailbreak. It seems like the only way for you to solve this problem is to wait for upcoming software or hardware unlock by iOS hackers community. Those iPhone 4S users who use Gevey SIM Ultra to unlock basebands 1.0.11, 1.0.13 and 1.0.13 MUST avoid upgrading to iOS 5.1. There’s no baseband 04.12.01 or 2.0.10 unlock available right now. There’s also no software solution for iOS 5.1 unlock baseband 4.12.01 but you could try alternative ways.
