Handy Shell is a fabulous piece of software for the 5800, making much better use of the real estate on the 5800s screen that the normal Nokia Standby page.
However it's not cheap.
But it appears that www.s60.com are offering a free license for it (and handy weather I assume)
First register or log-in to www.s60.com
Click on My S60 then click on My Exclusives on the next line down and you should see the offer of a free license for Handy Shell at the bottom of the page.
No idea how long this offer will last so best not to wait around for long.
