Home screen, offering the facility to replace your existing SUBCARD, etc.; finding my nearest SUBWAY - note that I'm a long way out of London - oops!; starting to place an order
Refining the order, options for bread type, extras, salads and much, much more - you've been to a SUBWAY, right?
Adding a drink and some cookies; checking out; nice to have some comprehensive FAQs and other documentation all within the application
Rather curiously, there's no way to exit the application. It probably doesn't matter, since Symbian OS now works so well with Qt - I doubt the application uses up significant resources when idling in the background. But an 'exit' button would still have been nice, developers please note.
In the meantime, go grab SUBWAY Express from the Nokia Store.
