How to unlock Bootloader on Sony Xperia neo V
Here's some info on relocking the bootloader anyway, but I'd suggest you find and try some roms instead from the Xperia Neo V Android Development forum. Edit I'd like to add that I consider it bad form to downvote my answer, as there was no information available when I posted this answer on whether your bootloader was unlocked or not. The open developer community is important to us at Sony, and we have therefore made it possible to unlock the boot loader for certain releases of Xperia™ smartphones from 2011 and onwards. To find out what phone models are supported by this service, please see the Supported phones box on the left.
