... For info series 40 phones are a basic menu list, shown page at a time, with a set amount of memory assigned to each page. Series 60 phones have a communal memory, meaning they can have more than one page or application open at any time. Making Multitasking possible.....and allowing other applications to be added, such as tomtom etc
So there you go.
