I just installed the version from the OP in this thread and can confirm that on my stock ROM everything works perfectly with no warnings! See the procedure that I wrote here.Unrooted shouldn't see it. I can't confirm tho... my phones been rooted from day one. Maybe someone with stock ROM can chime in and help more.
