Wow.. there are tons of things that can be changed by editing the .provxml files in OEM\_OperatorPKG
in mxipupdate_oemoperators_104.provxml I found my font size mod i was looking for, change 1000 to 800 for the "value" and 96DPI to 192DPI for the reg key to get the 1 size smaller font (old default on titan/apache)...
<!-- Font size 4 (now 3) from Left -->
<characteristic type="HKLM\ControlPanel\Stylus\192DPI" translation="filesystem">
<parm name="CurFont" datatype="integer" value="800" />
</characteristic>
also changed PIE default home page:
<!-- Default PIE page -->
<characteristic type="HKLM\SOFTWARE\Microsoft\Internet Explorer\AboutURLs" translation="filesystem">
<parm name="home" datatype="string" value="http://www.google.com"/>
</characteristic>
These files just seem like registry mods added by VZW... its interesting to read some of the code comments...
Theres lots of great stuff in that folder... even the VZ splash screen gif which is getting replaced soon...
