For developers and Android DIYers, having a locked bootloader can be troublesome. While other Android smartphones are easier to unlock than other, the Galaxy S III on Verizon is one of those where it just is plain annoying.

Till then, the $199 locked bootloader version on Verizon seems like the more compelling offer, also considering that all other carriers offer the Galaxy S III with an unlocked bootloader, without the premium charge..
