BlackBerry app with geolocation features

The application is a bar and event finder. Bar locations can be determined by GPS or AGPPS. Events are supposed to be pushed, or pulled via a feed from our site using a key. 1. We would like to have bar locations displayed on a map and also the current location of the handheld user. 2. We would like to have the ability to update bar information. Therefore on first load of the application and every 5 to 10 days after, this information should also be pulled from our site using a key. Include a force refresh button If you have a preference on how this information should be represented, please tell us. Business information: a. Name b. Location; long and lat c. Address d. Hours of business e. Brief description 3. We would like to have the ability to list events. Event information should include: a. Name b. Location; c. Address d. Description e. Start and End time of event f. Events should be automatically expired. 4. We would like the app to display a news feed, eg a Twitter feed, within the app. 5. We would like the app to support barcodes, so that we would be able to track customers for participation in promotions such as free or discounted entry to events, etc. 6. The ability to record, optionally, the user’s email address. We would not need the ability for users to create accounts to access the app’s features. Only the email address need be recorded. 7. The ability for users to report a location where the product is not currently available. 8. There would be a refresh timeout, which would automatically refresh the news feed within the app. Also, there would need to be a Force Refresh menu item for the user to manually refresh the feed. 9. Facebook “Like” button which would open the appropriate page in the phone browser.
