I don't they going to do that because I think all the instrument plugins in Logic were made by the emagic team before they moved on (efm plugin probably stands for emagic frequency modulator like how es1 and es2 stands for emagic synthesizer). I think for them to port the UB to the iphone/ ipad, they would have to bring in the emagic team to help with porting process and Apple isn't trying to do that. Apple's focus is on Garageband more than Logic. I think soon they're gonna get rid of Logic Express and turn it into Garageband Studio or something like that.
