One app my fianc�s iphone has is a barcode storage system.... All those annoying cards and keyring tags are not needed..... You punch in the numbers your grocerystore or departmentstore scan card has and the iphone can display the barcode on its screen. talk about convenience!
Alk searches done for blackberry+barcode+app returns a barcode reader app. Maybe somebody out there could write one and out it in the crackberry store, I know it would sell bigtime.
