OK. So while tinkering with my system media files (battery low sound for example) I noticed that my g2x has a filed called 'BatteryLow_InCall' in my system/media/audio/ui folder, yet the 'system dump' you uploaded here does not have said file (batterylow_incall).
I noticed you were rooted with the superuser.apk being included in your system dump... did you remove that file at some point before uploading said file dump? Not a huge issue as I have that particular file backed up anyways... just raising the concern that this isn't the entire collection of system files apparently... (unless I missed something).
