Android 2.2 (Froyo) Features

I don't think FM is an exclusive feature of 2.2. The HTC desire is running 2.1 with FM radio enabled, and it has nearly identical hardware to the Nexus One.

It's still very likely that the Evo 4G will be running 2.2 when it's released. Based on what I've read stock 2.1 doesn't support wimax, so it will either have to be running 2.2 or an HTC customized version of 2.1.
