Sarge,
It's not really WM5 versus WM6. More like carrier-rom versus kitchen rom.

The extended rom on the 6700 is a 9.9 MB flash partition that is set aside strictly for carrier (i.e. phone company) customizations that run after every hard reset. For Verizon, this includes the Arcsoft mms app and a number of cabs that set up your phone provisioning etc. For Sprint, it includes no mms app and a bunch of of junkware that nobody wants in addition to the basic provisioning. The kitchen now includes the good parts of the extended roms within the basic OS build, so there is absolutely no need to keep the extended rom intact.

I unlock it and install programs there.
