There is quite a bit of information about processing InBox and inBox entries in the Forum already, just search for it.
To traverse the InBox you actually use the standard PIM API which is integrated into the Blackberry. Here is one Thread that talks about this, in the context of listing the messages in the InBox
I am expecting that reviewing the forum entries and KB articles you will find if you search, plus the API documentation, you should be able do what you want, but if you have any specific questions, please come back to us.
