thanks for your reply.
One more thing :
I want to know which fonts are included or can be used for browsing in te Nokia 3650 and the Sony Ericsson P800? (i want to add in CSS font-family attribute, but I don't know which are the available fonts for each terminal)
I suggest you download a application that can read the memory of N3650 or P800, such as the free trial version of seleQ from http://www.ximplify.com/nokia-3650-symbian-main.htm
With this SW you can go to Z:\System\Fonts and check the fonts N3650 supports.
Whether the mobile browser uses different font types with the OS, I am not sure.
