Android 2.2 (Codename: Frozen Yoghurt) brings a new feature which allows moving apps to the SD card. Unfortunately this only works for apps which bring a flag to allow this, i.e. not for the current versions.

sudo ./adb shell pm setInstallLocation 2
Valid values are:
0— Automatic (app decides, default)
1— internal memory preferred
2— storage card preferred
