Although not affiliated with me, here's a helpful link for all Symbian S60v5 users as well as S60v3 users. If you feel that the theme that comes with the Nokia 5800 is a bit dull, then you should check it out - theme developer PiZero has quite a few high quality themes now compatible and optimised for the S60v5 platform, so it's definitely worth taking a look. Good news is that they won't cost you anything, so get downloading!
