I need an app for BlackBerry phones for my customers in my restaurant business. The customer upon checkout would earn points based on their invoice/receipt and when they refer to friends about the business and their friends makes a purchase the person who referred them would also get points added to their credits.
App must be able to push info to the BlackBerry phones notifying them of specials or deals etc.
App must be able to post your comments and referrals to facebook also.
We have recently done exactly one similar application, with lot more features than listed in this project description. I can send you demo of my app. Please check attachment.
