I have Java code which I have written for a customized contact list application for a Blackberry PDA. I need someone to write a small function within the application that will replicate the find feature on the main Address Book. What this does is filter the entire contact list based on the contents on one edit field and provide you with a new list of substring matches. I will also need a couple of small tweaks to the application such as a facility to wipe out the persistent store of contacts via menu selection or automated via command from a server. The Blackberry JDE is freely available and comes with a full simulator so this project should be very easy to complete.
