N00b Fail. Galaxy Tab in Force Close Loop

I've scoured the interwebs for the solution and I can't find one. I was hoping that you could help.

So my husband bought me a Galaxy Tab 7". Its a Sprint, but I'm planning on using it on WiFi only. The only reason it's Sprint is a Woot Special. I promptly rooted it and began uninstalling Samsung's crapware.
So I uninstalled the wrong thing. I think it may have been the messaging 2.2 app. I uninstalled it because I'm not planning on ever using SMS on this. I now get the following force close:

"The application Network Manager (process com.android.phone) has stopped unexpectedly. Please try again."

I've been searching the last two hours for a soultion and no luck. The app doesn't seem to be restoring from Titanium Backup either.
