EHS 2.1 APK's

Just wanted to check the difference between the two APK files which are selectively installed by the EHS 2.1 Installer:

 

ehs_mot.apk

ehs_symbol.apk

 

I assume that ehs_mot is used for Motorola branded OS versions and ehs_symbol for Symbol branded OS's but could someone please confirm?

 

Thanks in advance,

Ian Hatton
