what i did is the following; i went to the bluetooth devices on my pc and remove the previuos configuration on my n900, after that i remove all the paired config of devices of my cell, then i switch off the bluetooth on my cell and pc, then i restarted the bluetooth on both devices (pc and cell) and open bluemaemo and paired them as ussually but this time i gave some time to the "waiting for connection" on the bluemaemo screen and the i look on my pc that when the device (cell) got connected to the pc it showed an icon like a keyboard instead of the cell icon that ussually appears, so after that on the cell appeared the screen where u can acces to all the differents actions (mouse,keyboard,presentations etc) now the cell was connected with bluemaemo and it works really really good, i can do everything with this.


something even better to follow:
1. delete the bluetooth phone entry on your pc if it's already there
2. delete the bluetooth pc entry on your phone if it's already there
(so afterwards both devices shouldn't "know" each other ^^)
3. make sure that bluetooth on both devices is disabled
4. start bluemaemo on n900
5. click on "wait for connection"
6. activate bluetooth on your pc and search for devices
(n900 should be recognized as "other" or "hid" - not as phone afaik)
7. pair both devices
8. the "waiting for connection..." window on the n900 should disappear and it should show the bluemaemo menu
9. now it should work properly ^^
(10. if not - maybe restart your pc and try again)
(11. if step 10 doesn't help make steps 1 - 9 again... i had to do it several times too before it worked for me)
