Update your firmware to PR1.1, or at least PR1.0.1. All the cool kids are doing it. Live with blue squares. Source some icons with the filenames above to put in /usr/share/icons/hicolor/64x64/hildon. Theoretically, I could ship some with Catorise, but I'm not sure I want to (I can't ship the Nokia icons, after all).
[Firmware updates don't necessarily update the hostname :-)
