MC 7455 Latest available generic FW

Hi everybody.

I would like to know if the generic FW SWI9X30C_02.30.03.00 002.046_001 GCF Approved—Release 24 listed for the MC 7430 will work with my MC7455 as well.

I found also this one from the sierra website : Generic SWI9X30C_02.32.11.00 002.064_000
PTCRB & GCF Approved—Release 26.

What means CGF approved and PTCRB & GCF approved.

Which one should i use…?

Thanks in advance.
