Hi guys. So I have an iPhone 3GS jailbroken to IOS 6 using evasion, with baseband 05.16.05, serial number: xx937xxxxxx. But I'm a little confused about unlocking it. Basically I will send this phone to Dominican Republic, to a very deserving young girl graduating with honors, bit I don't know if I need to unlock it at all... If I do, I wouldn't know where to start. I see upgrade methods to other basebands and downgrade methods that seemed to not apply to my case (not sure). I see manual methonds (SAM Unlock) that seem to no longer work. And I also see ebay unlockers that seem to do it by only using your IMEI number, and seem to be very successful, but I wouldn't know how they do it. Any help on my case?
