If you have an iPhone 3G or 3GS and need an unlock for your phone then most probably you know about the 06.15.00 unlock method with ultrasn0w 1.2, but if you use that method there is no method of going back i.e. you will stuck with this baseband will lose warranty as it will expose your iPhone to apple, but you don’t worry as I have found a solution to that to. 
If you have Modem Firmware 5.13.04 or below then follow the Steps Below
Tools needed
