No expert, but i would not believe it would work or you would have already ready about it, and the x and x2 have different hardware, so it will most likely brick your phone.
I wondered the same but also thought that someone would mention it if it was possible.
I really hope that GB has the impact on this thing like it did the original X.
I thought the same thing. If it were not for the different equipment, one of the developers either here or in XDA would have already mod-ed it for the X2. Wait or have a $450 brick.
