Nokia recently announced its latest firmware 1.2009.44.1. It’s meant to answer several OS issues. It’s available through NSU (Nokia Software Update).
Be sure to backup all your data if you wish to upgrade to the latest firmware.
I will get back to you once I’ve updated my N900. Ciao
1. I just checked the Application Manager and found out that it now sports a new GUI. Good work Nokia.
2. Once an application is installed, you will be returned to the previous spot you were before. This is practically more convenient than before.
