Unlock iPhone 3GS iOS 6.1.3 baseband 05.16.08 Using Redsn0w and Ultrasn0w

Unbelievable method to unlock with Ultrasn0w iPhone 3GS on iOS 6.1.3 baseband 05.16.08 (which is not supported by Ultrasn0w). To be honest I found the video on YouTube where the user ultimateidevicevids, showed interesting way to unlock 6.1.3 baseband with famous tool.
Last time I showed you how to use Ultrasn0w on iOS 6.1.3 iPhone 4, 3GSwith old (preserved) baseband but here below you will definatelly find something new.

There are four phases to do. First you will need to jailbreak your device. Then to install iPad baseband (06.15.00). After – downgrade from iPad baseband and install Ultrasn0w to get the signal.
Attention: As for me I didn’t test this method and installing 06.15.00 may harm your device. So think twice before following steps below. This method is shown on AT&T iPhone to unlock it for T-Mobile. But if your device is locked to AT&T I have a better idea for you. Why spend your time and efforts together with the risk of corrupting the iPhone if you can buy AT&T iPhone unlock only for $9.99. Plus, your iPhone will be officially unlocked which means you can update iOS and baseband in iTunes and your device will be never be locked again.
But if you decided to give a shot we can start.

How To Unlock iPhone 3GS iOS 6.1.3 Baseband 05.16.08

Note: This guide is not working for all 3GS models. It will work only if your device was made before the 34 week of 2011. To check it look at the third, the fourth and the fifth digits of the serial number. The third is a year (if there is 1 – it is 2011), the fourth and the fifth is a week.
Be serious about that and check your compability. Otherwise your device may become a brick.
Step 1. Download redsn0w and iOS 6.0 firmware file on your computer in the same folder or the desktop:
Step 2. Launch redsn0w as Administrator and go to Extras -> Select IPSW and select iOS 6.0 firmware you downloaded in step 1.
