I don’t have a JesusPhone, so I can’t say for sure, but this thing looks mighty cool. I don’t think you’re going to be hitting Van Halen heights of guitar heroism with it, but you might be able to get to Family Guy “douchebag” levels. Someone install this right now and tell us all if it works. It’s been tested with 1.1.1 but as I believe we are somewhat advanced past that now, you do this at your own risk.
Update: We have one Ashley telling us it works with 1.1.2 and sounds good. Thanks!
