I would keep Thunderbird 2 for now as Thunderbird 3 is only a Release  
Candidate.

It some times pays to run 'apt-get dist-upgrade' in when packages are held  
back as something might require deleting and Synaptic uses safe-upgrade  
normally (you can alter this in preferences) and won’t delete packages  
when updating.
