These are instructions on how to jailbreak and unlock your iPhone 3G and 3GS using BlackRa1n and BlackSn0w for Windows.

These instructions will work with the 3.1.2 firmware, the 05.11.07 baseband, and iPhones which require hactivation. If you have already jailbroken following these instructions to unlock will be easier.

For those with a new iPhone 3GS (updated Bootrom), BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it.

Before continuing make sure you are on the 05.11.07 baseband by following this tutorial. If you are on 5.12.01 or higher, unfortunately you CANNOT jailbreak as of yet. If your baseband is lower than 05.11.07 then you must restore to the 3.1.2 firmware for the iPhone 3G or 3GS. You can do this by opening iTunes, selecting your iPhone from the list of devices on the left, then hold down the Shift key and click Restore.

You can find the Mac version of this tutorial here. Ok lets begin...

Thanks for the post.I would like to share my experience in unlocking my iPhone 3GS.I wanted to unlock it from the respective locked network but did not want to jailbreak it.As jailbreak makes the user to lose the warranty of the phone.I was also not comfortable in using the available unlocking tools.I searched and found that provides such a permanent unlocking service for iPhone models.They unlock the iPhone through the remote unlock service which would be a better option because,we need not give the mobile to someone else nor do we have any chance to enter the wrong unlock codes.This type of unlocking was very apt for me.I unlocked my mobile and now free to switch networks.

The cell phone spy software can be useful for many things including monitoring your kids, wife, employees or other. It is important to know what people in your life are doing, and make sure there are not up to anything they shouldn't be!

Are you thinking of how to get rid of cellulite? Cellulite is most common among women. Cellulites are basically fat cells that protrude up the skin and create a dimple appearance.
