Samsung Galaxy S5 unlock bootloader Verizon to come eventually

Ive had the S5 since October and i just got around to rooting the Verizon version and putting safestrap on it i know there is rom for the verizon Galaxy S5 but my question is will there ever be a bootloader unlock method for the verizon and at&t versions of the S5 any thoughts because i dont feel safe flashing a rom on a locked bootloader i had a droid razr m before this phone i had the bootloader unlocked and was running cm11 i just wish i could flash a well know rom on my Galaxy S5
Most likely not. Verizon do sell a dev version of the phone with an unlocked bootloader and it's got CM thanks to albinoman and ktoonsez

if ur not comfortable flashing roms on a locked BL (is safer) than buy a dev ed s5 or another device thats unlocked or just stay stock lol

Rooted s5- unlocking ?

Hi,
I just got Galaxy S5 900F locked to vodafone uk. I found a tutorial called UNLOCK, flash and root your s5 4.4.2. It was actually comming from this website. I rooted it but it is still locked. I think rooting didn't really unlock my phone(as tutorial said) as it wants me to type the sim code in. Is there any way to unlock it free? If it isn't whats the cheappest way? Thanks
