I made a mistake and upgraded my iphoone and i went to stores and they say it couldnt be unlocked what do i do i need help?
You can download a downgrade in firmware for the iphone from felix bruns website. Then when you open up itunes you can choose which firmware file to use for a restore by holding down the shift key when you hit the restore tab. Then choose the lower firmware version you downloaded. Once you have downgraded your firmware, blackra1n is the software you need to unlock and jailbreak it. It is extremely user friendly, and google is your friend to find it free. Remember to back up all of the data on your iphone before tryng any of these proceedures. Good luck!
