Free Iphone Unlock

iOS hacker and developer NotCom or also known as semaphore allows you to back up the SHSH blobs (ECID SHSH) so you can downgrade to an older version of the iOS and released a new tool named TinyCFW for iPhone 4 and iPad 2 users.
TinyCFW allows iPhone 4 and iPad 2 users who have taken backup of iOS 4.3.3. SHSH blobs to downgrade from iOS 5.0 to iOS 4.3.3.
NotCom explains that the TinyCFW is a simple tool that he put together for a friend. His friend has an iPad2 GSM and has his 4.3.3 SHSH but since Apple is no longer signing 4.3.3, it isn’t possible to downgrade to 4.3.3 without getting stuck in a 1015 recovery loop.
Here’s what TinyCFW can do:
It will modify an existing ipsw for an ipad2 gsm/cdma or iphone4 gsm/cdma
It WILL modify the ipsw TO UPDATE YOUR BASEBAND TO THE LATEST!
It will create an ipsw that you can use with TinyUmbrella AND iTunes to restore to a version of iOS that you have SHSHs for.
It is primarily for iPad2 with a baseband OR iPhone 4.
NotCom also made it clear that the TinyCFW is not a jailbreak, an unlock, a tool to protect your baseband, a restoring device. The TinyCFW is not also meant for iPhone 3GS and 3G, iPad and iPad 4S.
He has also provided the following instructions to use TinyCFW:
The usage is simple. Start the application. Once the window comes up, click the top button and choose an ipsw for which you have SHSHs for. The app will scan it and tell you the firmware and baseband versions in the ipsw you selected and the firmware and baseband versions that will be in the target ipsw when you click the second button. If you’re ready, click ‘Save Target IPSW’. This will take a minute or two and when it is finished, you will have a file named:
.bbupdate.ipsw.
You can use this ipsw with iTunes and TinyUmbrella to restore your iPad2 GSM/CDMA back to say 4.3.3 (if you have 4.3.3 SHSH).
NotCom has mentioned that he plans to include this functionality in TinyPwn and expects it to be far more robust then this initial version. So please proceed with caution.

It was just yesterday when the not official version of JailbreakMe for iPad 2 was released and here we tell you how it was leaked. With this leakage, they have completely laid to waste the work of Comex who put in a total of 10 months of hard work for it. However, everyone from the supporters of Jailbreak are also worried that through this leak, Apple may have the chance to fix such abuse even before the official version comes out. According to Comex, he utilized a PDF exploit just similar to the JailbreakMe 2.0.

The last time that he released this, Apple was fast acting in releasing a software update in a period that is even less than two weeks so that the iOS can be fixed and protected. Comex expects the same to happen this time around unless its users would create a backup for the SHSH blobs. Ionic, is also another popular developer of the jailbreak for iOS 4.3.3, tools used to jailbreak Snowbreeze, RedsnOw, Pwnage Tool and a lot more. They also believed that with this leakage Apple can possibly kill the jailbreak as early as before the 4.3.4 gets out.

You can utilize the TinyUmbrella for the iOS 4.3.3 to be able to make a backup of the SHSH blobs so as to downgrade to the old version of the iOS once Apple makes software updates. It will be very exciting to how fast Apple would react and if Comex will still release his official version for the tools of the iOS 4.3.4.
