I wanted to introduce Vesuvian software, who have built a new portfolio of Nokia 5800 applications using Java. Now, Java and the 5800 are traditionally seen as awkward bedfellows, but these are touch-enabled, work full screen and rather well. And they're all free. See Hack Proof Password manager, Notes on the Phone, Touch Calc (a scientific calculator), ScratchPad, XpressDrums (a fabulously intuitive drum machine/sequencer) and SuDoKu SoftTouch. Oh, and if you use a S60 3rd Edition phone, then most of these apps, plus a few more, are also available for your device, too. Enjoy.
