New firmware update for Nokia 5800 v. 50.0.005

New firmware v.50.0.005 now available for installation.

What's new I've got with this update:

• kinetic scrolling in main menu
• performance optimization

I try to install this via Ovi Suite with phone connected by USB cable.
I've got following issues:

1. Firmware update demands 1Gb of free space on my hard drive. For what?!! ok...
2. Nokia Ovi Suite demands update
