EDIT 8/1/10 9:16PM CST:
According to @comex the bug was caused by the bootstrap including /var/mobile, /var/mobile/Library/, and /var/mobile/Library/Preferences with incorrect permissions and causing CommCenter to be unable to read the carrier plist. The official fix will be rolled out as a a critical update in Cydia and new jailbreaks as of a few minutes ago no longer have this issue.
EDIT 8/1/10 9:49PM CST:
@PlanetBeing is now sharing another method to fix for FaceTime/MMS on Twitter:
"For existing users, chmod 755 /private/var/mobile/Library; chmod 755 /private/var/mobile/Library/Preference then Reset Network Settings"
EDIT 8/1/10 10:47PM CST:
You should now be able to go into the Changes tab in Cydia and click update and have FaceTime and MMS work.
