I have added the beginning of a new project for the Blackberry. It has a dependency of the 4.5 or later OS to work thus far. Thanks to Daniel for helping contribute too.
So far only the main screen works by reading the MLS Membership file directly from the SD card, as only 5.0 can read the new SQLite database. Still need to try and persist the data that is in memory so we don't have to read the file each time, but we are making progress.
