It'll be a $50 fee and its done via MobileTechVideos. There is no XDA exploit to unlock the bootloader on 4.3+.

Yes, and a couple weeks.

All the information is available on their website, Google it.

thanks for the info. Now while looking on the site I ran across JTAG i think and i was wondering what it is. Also, could i install custom ROMS with custom recovery on galaxy S4 without sending it in and without using SafeStrap

JTAG stands for joint test action group, which is essentially a common IEEE serial port located on the motherboard of many devices. In a phones case, a Riff box is used to access the port and flash device specific files to the motherboard directly, thus eliminating the need for the phone to be on or functioning in the first place.

In this case, the jtag port is used to write to the emmc chip directly to override the system check and flash earlier firmware.

You can on the S4 but you need MDK firmware, you're better off asking in the S4 forum.

Ill look into the s4 forum. So is there anything I could do to run LiquidSmooth ROM on my S3? Also, would it be possible that Verizon unlock it if I ask?

Only way is by paying $50. Verizon will do no such thing. Verizon only releases sim unlocked phones, Verizon has never provided a bootloader unlock service.
