I have unlocked my 2.3.5 bootloader. It only works from a specific situation so far though.
-I have NEVER done an sbf
-My Electrify was shipped with 2.3.5, not updated from 2.3.4 via OTA
If you fit both of these qualifications go to teamuscellular .com, electrify development forum and the thread titled 2.3.5 locked bootloader work around/fastboot and follow the guide in post #72. (sorry, can't post links yet)
I would encourage reading the entire thread, its a bit confusing but worth it.
