Hi Guys!

Ive had to restore my phone a couple of times now.
What I notice is, after a restore, not every file is returned back to factory setting. For example the international caller ID file is still "my" version instead of the factory iPhone version.
That makes me wonder, what other files stay left, changed by 3rd party software? It cant be good that lets say half of your iPhone remains "changed" and the other half is original made by the restore.

Does anyone know how to get the phone, except for the baseband for anysim of course, back to factory condition?

Im not talking about virginizing here because that is only restoring the baseband. Im talking about a all factory iPhone files restore.
