Hello All,

I just picked up a ATT 9900 and was able to use DM to change devices and sync.

When I went to sync again it wants to delete all bdays and numerous calendar entries. I aborted the sync.

Any ideas?

There's your problem. Device switch is known to cause many different issues on this device when upgrading from a prior OS. There's a bulletin on RIM's site somewhere on that. Best thing you can do now is a full OS/Data wipe and selective restore. You can use JL commander for this, or Javaloader from RIM.
