Dear RK,
MS Behavior Modified indicates whether the phone’s behavior has been changed from the default.
B: Modification is not related to channel selection (means changes are related to Multiband reporting, cell adjacent scan, forced power class, Band locking, channel quality)
C: Modification is related to channel selection (cell bar ignor, target / prevent HO etc)
G: Modification of GPRS related behavior. (Forced GPRS, multislot class etc.
Regards,
