Well I managed to connect the phone as suggested.

I did a clean reflash and installed just backupmenu, then I have connected the phone and launched GParted. I have chosen the phone and saw the partitions. After unmounting them I was able to partition it. So I have chosen the 27GB partition and resized it to 23GB. This gave me 4GB space which I have chosen and marked as extended partition and the I have chosen ext3 type while creating a new partition inside the extended one. All went well but after starting maemo I couldn't see it.

In GParted there was the large partition, the my new one, then I think swap or opt. Something like this. In the wiki it stated that I should not change anything so does this mean that I have to repartition everything from scrach and create a new MyDocs (if so what to chose in GParted so it would be MyDocs), new swap, new opt and only then put the partition for ED?

Huh the need for speed is killing me To much linux for a historian like me!
