Im trying to find a turbo sim on ebay as the one i already got doesnt work turns out its only for US.

But upon looking ive found that most of them say about how to check your firmware. It says if your phones serial number is 7v745 or above then you have the new bootloader 4.6 which is obviously unlockable.

But the thing that interested me is that my serial number starts with 7v743. If the information is correct then surely my phone has the previous bootloader that is unlockable???

Can anyone clear this up?
