Auf theunwired ist ein interessanter Artikel (bzw. eigentlich ists eine Zusammenfassung) der Updates der einzelnen Hersteller:
the::unwired - PERSPECTIVE: German Carrier and Manufacture outlook on Android Upgrades
Der Absatz bzgl. Samsung besagt
"""
Samsung, which is offering firmware updates by itself - not via Google - wasn't able to comment on GT-I7500 Galaxy upgrades. The Samsung Galaxy, which is available exclusively from O2 Germany, is the last (and only) available Android smartphone in Germany which is still running on Android 1.5
Cupcake. It even hasn't received an Android 1.6 upgrade yet.
