+Both of the above are hybrid configurations in that they use the new TCS3
+versions of the G23M protocol stack and ACI (Application Control Interface)
+firmware components grafted on top of the TCS211 chipsetsw foundation, resulting
+in a fully built-from-source configuration without major blob components.  The
+UI layers BMI and MFW in the UI-enabled hybrid-ui-vo config also come from the
+new TCS3 source, not the old version of unknown origin.  They are "voice only"
+configs in that CSD, fax and GPRS functions are disabled - these functions
+cannot be made use of on Mot C1xx phones, and disabling them significantly
+reduces the weight of the firmware.

+For the C139/140 target (but not for C11x/12x), it is also possible to build

+however, those configuration are now officially deprecated except for only two
+remaining use cases which do not apply to Mot C1xx targets, hence they are no
+longer supported officially.
