The Blade II is nothing to do with the SFII. Its a different phone altogether. It was always considered as the Blade II because the architecture is the same but their was a Blade II due out so no way jose! Don`t they faff about with these names? I suppose with the sleight of hand and slight changes they make them look like totally new phones and get more money in for them.
*** Just remember, any ROM change, Kernel change or any other type of change you do is at your own risk. Someone helping you is not responsible for any risks you decide to take. It works for many but their are situations, events and errors outside of the control of a third party that may cause a bricked phone. Think before you start. I took the chance and thankfully it worked for me. Had it not then only I would have been to blame. ***
