[QUOTE=orava;1243812]v4.3.0 for N900 is available here.

Installation
1. Make sure you have latest Qt Mobility 1.2 libraries installed. If you have extras-devel repository enabled you can install those with "apt-get install libqtm-12=1:1.2.0+git20111104-0nd~fremantle5" or if you don't you can download libraries from here (and install with "dpkg -i libqtm-12_1.2.0+git20111104-0nd~fremantle5_armel.deb").
2. Download .deb file from the link above and install it.

My Settings sheet is totally empty after upgrading the old 4.0.0 version to the 4.3.0. Map is some open street. How to get the terrain map of previous version back? Another question about the Qt Mobility installation guide: Does the command refer to X-terminal command? If yes, how to type the "~"? If not what does that refer to?
