Some people as I have noticed can not adequately distinguish between S60 i.e Symbian phones and S40 i.e Java Phones. So I’ve taken it up to myself to at least help in one way or the other.
Lets talk computer-wise now. Java phones are single-tasking phones that mostly can only do one thing at a time, less functions, use the application extension .jar and so much more. While on the other hand, Symbian phones are the multi-tasking, multi purposed ones. They can perform various tasks at once. Switch windows(you get what I mean) and are pretty fun to use. If you are interested in getting a Symbian phone, here is a list of some of them.
