Fixed the exchange contacts sync issue. The reason it isn't working is because WorkContacts.apk was missing. I installed the one from the TBH 2.3.230 release and that resolved the issue. Simply drop it into the system/app folder, give correct permissions and then reboot to have working corporate contact sync. Figured this out by comparing app files in the TBH release to Drod's latest Blurry release to see what app might be missing that is needed. Now I can say this will be the release I use for awhile.
