No special configuration really, after I stopped using it as my main phone a year ago, I reflashed with stock Nokia PR 1.3 and only installed handfull of programs.. There is no sim card in it, I only use it for the IM functions, some browsing, internet radio, cutetube and some gaming. Now after 100 days I can say it doesn't really like to multitask, if I have 5 - 6 things running it lags a lot when switching between them. If I lock the screen with something QT based running in the background, after unlocking again it takes up to a minute for the phone to get to a usable state.

I'll probably give it a restart as a christmas present, it has earned it
