I just went through the instructions on the Sony's website for getting the unlock code and then followed Ridder's guide and the install ran without any trouble (I'm not entirely sure if his process will work with other roms, can someone confirm this?)
I'm now off Verizon's horrible rom and running CM9 .
Anyways I just wanted to let people know, enjoy
*If youre having trouble with flashtool, try doing it using using the methods discussed in the links I provided above (Sony Instructions and Ridder). Alsomake sure you have Sony's Fastboot drivers installed.
