well for what i understand, the 7100 is an iden series blackberry and the 8350i is an iden series phone. i dont think they have any other iden blackberrys.
the 8330 is on the cdma side of boostmobile, not iden. so "technically" any blackberry offered on sprint or verizon can be flashed and work with boost, but only the $50 plan. the service books are not supported through boostmobile and you will not get customer support.
so any balckberry from verizon or sprint should work, to an extent.
