Thank you very much for answering the call for help in the channel and having a go! It would help me immensly if you could take me through the procedure you used to compile PhoneME Advanced mr2, as I would like to try and replicate the results with PhoneME Feature mr4 as this contains a more recent version of MIDP, which I am hoping will launch opera mini 4. Bear in mind I am a novice at this and have only just learned how to chroot into the sdk image on my N900 I had a go at running with the following command: cd /opt/phoneme ./bin/cvm -jar /home/opt/opera-mini-4.2.18887-advanced-en.jar Got error message jar: Could not find Main-Class manifest attribute Does this mean it is looking for variables pointing to the main j2se installation? if it is of any help I found a thread used by devs earleir in 2010 regarding building for N800 and N900. http://www.gossamer-threads.com/list...velopers/60613
