v3.4.8 for N900 is available for download from here. It uses Qt Mobility 1.2 from now on and you'll need latest Qt Mobility library installled. If you have extras-devel repository enabled you can install it with "apt-get install libqtm-12=1:1.2.0+git20111104-0nd~fremantle5" or if you don't you can download it from here. If you have manually installed Qt Mobility 1.1 libraries to get earlier versions of Mapsi working you can now remove those. See this post for new features and install instructions. I will push this to extras-devel repository if someone confirms that it is working.
