If you break it down without the "x" then you can recreate the "x" variant with the actual numerical identifier .. For 8660/8960 you just would do as much of a unification as with the others.. You could still use 8x60 to identify those two, you just wouldn't use it as often. Daniel -- Sent by a consultant of the Qualcomm Innovation Center, Inc.
