How can you bypass iPhone security lock?

Pre-requisites: 1. Download required firmware (2.0 / 1.1.4 / 1.1.3 / 1.1.2) from www.tuaw.com (LOL where I got 1.1.4 - 162MB).

2. ziphone.exe to bootloader downgrade / unlock / jailbreak, refurbish also (I've version 3.0)

3. Get installed iTunes latest version in your PC (I'm using iTunes 7.6.0.29).

4. internet connection

(make ensure that you have met all pre-requisites before going ahead for step-by-step procedure) Step-by-Step: 1. Plug the iphone in to ur PC, hold the power button and then slide to power off. 2. Press the power button, as soon as the Apple logo appears press and hold both the top power button and the home button together until the "iTunes & connecting Wire icon" appears in your iphone. (This will put the iphone into restore mode). 3. iTunes will open up automatically in ur PC. 4. iTunes will ask to check for the updates over internet, Click on "CHECK" button. 5. Give some time to it, now u can see "UPDATE" & "RESTORE" button in iTunes, middle of your iTunes window. 6. Hold down "SHIFT" key in ur keyboard + Click on "RESTORE" button in iTunes. 7. It will ask for FIRMWARE RESTORATION file, Browse for the downloaded firmware file , select it & click on Open button in browse window. 8. Wait for 5mins, It will restore your iphone to factory settings, iphone will restart, then it will ask to insert unlocked / AT & T SIM card(Dont get panic).

(Make ensure that till this step (Step 8) internet connection is on). 9. (Disconnect internet connection for safety purpose, even connection nothing goes wrong)

Start ziphone.exe click on "DO IT ALL" button & wait for 5mins(Dont get panic by seeing lines of code scrolling in ur iphone), iphone will restart & ur iphone is ready to use any SIM & enjoy. (I'll not be responsible for any damage due to the above procedure, go ahead with ur own risk). Any issues feel free to write to me @ u.spice@Yahoo.co.in
