I think the general consensus on XDA is that the latest update to facebook is causing the fc.
Neither reinstalling, nor fixing permissions seem to help the people that are getting it.

Also, if you're having 3g issues, I would try starting from a clean wipe, then testing 3g on the stock kernel. If it works, then try Tiamat. If you are in an area where you normally get 3g, something is def not right.
