Over on the blade forum ( dual boot mode rom's) have been made to work and I believe a person called "Jinxx " said it also works on this phone. Now with the blade you could have 2 gen2 rom's on the phone. This is why I haven't tried it as it's quite simple to restore my nandroid on my blade and boot into a ICS rom with gen2 radio firmware.
What might be interesting is if this works on our phone ,would it be possible to have a Ginger bread rom to boot into on our sd card. Probably not but I am following this topic 24/7 and will report back when I have more understanding.
