A bit back Josep told me about this PicoWiki service. Turns out it is just a very simplified Wiki that you can work with easily from your BlackBerry browser. I found it to be a great way to create a mobile startpage for my BlackBerry with all the links I use personally. You even get a very easy to remember URL like www.picowiki.com/your_choice/ I set up a demo one for myself at www.picowiki.com/br/.
No the most revolutionary of services but it has a very easy to use interface from your desktop. If you were looking for an easy and cheap way to make your own mobile homepage for your BlackBerry then this might just be the solution for you.
