After recently upgrading my Sprint Pre to 2.1.0 via Meta-Doctor I learned quite a bit about how to repackage the .tar file to add/delete pre-loaded apps.

I noticed this in the 1.4.5 doctor in the Sprint.tar file. Anyone know what it is? It's not in the Sprint 2.0.1 doctor or in the Meta-Doctor 2.1.0 file.
