Until recently, Nokia 5800 customers have been complaining about some bugs in the v21 firmware. That was why Nokia has decided to release the updated firmware - the v30/v31 (depending on the product code of your phone). The updated firmware fixed some bugs and it has added a new home screen to the Nokia 5800 XM. What I'm more surprised is that there are many free softwares in the market to compete with the Iphone Applet Market!!!
In order for you to experience it, point your mouse to this website and click on 'forum'. You will be able to download some useful applications for your Nokia 5800 XM. The best of all, it's free and it is legal!!! You do get from applications to themes and ringing tones. Just browse on the webpage and you will be able to find your way through. I'm pretty impressed with the Nokia 5800 XM though. I think it's the best mid range mobile phone which Nokia has ever come up with. I hope that the successor of the Nokia 5800 will be even better than the Nokia 5800!!!
