Thanks Shmoove. In case other people need this info things you need to download are the Nokia S60 SDK and Nokia S40 SDK. Install these, they will automatically ask you for the JDK install path and WTK install path. Once this is done, in NB 4.0 goto Tools and select the Platform Manager option. From there all you need to do is add a new platform for J2ME - i.e. literally select the dir where the SDK for the relevant series is installed. Everything else is done for you, of course you will have to change the default emulator, but once you type in something like import com.nokia.mid.ui.FullCanvas and dont get any errors, then you know you're up and running. The Nokia emulators are nice... but will they actually be useful?!
