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.

There is a jailbreak app that allows your iPhone to snap a photo in the front camera when someone enters the wrong password and sends the photo and information (location with a map) to your email.
iCaughtU is one of the revolutionary jailbreak apps that can add security in your iPhone and helps the authorities to catch people who stole the device. The jailbreak app also does not allow someone to turn of the device while it is locked.
iCaughtU is available in Cydia App Store for free. However, iCaughtUPro is available for $2.5 and offers you a number of added features.
• Take a picture in the front camera when the user enters a wrong password or tries to turn off the device while locked and send it via email.
• Save the photo in the Photo Library.
• Set the number of max attempts before taking a picture.
• It can also send the location and time when sending the email.
• Send an SMS when someone entered a wrong password.
• Compatible with AndroidLock XT (Fully Recommended Tweak)
The developer is set to add more features in the app. The combination of Find My iPhone and iCaughtU apps make a very effective anti-theft system for the iOS device.
