I think the NokiaWorld blog was a very nice service from the Nokia event NokiaWorld. At this blog you find a lot of good information about new devices from Nokia!
One thing I found out was about WidSets, with WidSets you could create different service for the mobile phone. WidSets look very interesting for me as a JavaMe developer!
This because the WidSets is build on top of core JavaME and because of that compatible with a lot of models of mobiles phones. In Q1 2007, a dev kit will be released.
