BlackBerry Application for web-based application

I have? a? blackberry application that is used to enter time/expenses and other things for a subscription based? web based application called "eBillity".? ? The BB application? is having some issues & the original developer is unavailable.? The login is not working correctly.? I would need for someone to work with my web developer to get the webservices configured properly.? At one point the login was working correctly but the application was taking a very long time to load the data. There also needs to be some changes as to what data is loaded onto the local device when someone logs in.? The purpose for this application is for a user to choose a client and project that they would like to enter time or expenses for.? The data entry? is then transmitted to the database, so when the user logs into the web application the entry is there.? the device would need to download the users, clients, projects, expense types & amounts, billable entry types? & amounts, and user permissions, as well as other things.
