Convert Pocket PC program to Palm and Blackberry platform(repost)

The proposed project is to convert a Pocket PC application written in Visual [login to view URL] 2003 to a Palm OS and Blackberry application. The current application consists of a single form with a tabcontrol, several labels, three comboboxes, and two datagrids. It reads the contents of three XML files in order to dynamically fill the comboboxes. Based on the results of selection from two of the comboboxes, one of the datagrids is filled with two columns from a fourth XML file. The second datagrid is filled based on the selection of the third combobox. The completed conversion must be able to run on current? devices. The XML files must also remain separate from the main application so they can be changed and updated as necessary.
