Now you can decode any iPhone with baseband: 04.26.07, 05.11.07, 05.12.01, 05.13.04 using ultrasn0w! To be able to do the decoding, you must have a jailbroken phone and Cydia installed, it doesn't matter what firmware/baseband/bootloader/bootrom/etc! Here's how you can do the decoding :
Step 1
Open Cydia, go to source and add http://repo666.ultrasn0w.com
Step 2
After adding the source, go to search and search for ultrasn0w and install it.
Step 3
After finishing the installation, press the button that tells you that the phone will restart and wait.
After the restart, everything should be ok and the phone decoded!
UPDATE: it seems that a new update for ultrasn0w has appeared in Cydia, it would be good to install it! When information about him appears, I will let you know.
UPDATE 2: All those who do NOT have an internet connection can install ultrasn0w using the tutorial this.
