Hi,
I am unable to install simple_oc.
Installing mirall was easy, but neither apt-get nor Application Manager can find the package simple_oc.

I will try to download it directly. The link in the OP is dated, it points to version 1.0.1 which is no longer available...

[edit] one hour later, my good old N900 is in the process of syncing the first time, about 4000 files and 2.3 GB...

Great! Thanks a lot!
