It's still being determined which and when Android devices will receive Froyo. The Nokia N900 has been hacked so now its users can receive the Android 2.2 (Froyo). It's not the full thing just a sample of the Froyo for the "hackers choice" phone, reported by Android Central, it isn't exactly a very polished built however with missing key functionallity.
The Nokia N900 also has been experiencing some problems with its WiFi connectivity, cell signal, and mounting for the SD card. Well from tests seen it looks like the thing is running fairly smooth. So as the N900 receives sort of a "bootleg" version of the Android 2.2 we will wait and see what other actual Android-based devices get Froyo.
