This is another one of those times when we say you might well want to leave this to the professionals (or at least those of us too crazy to know better), but here's Froyo running on the Evo 4G. It's not the first time we've seen it, and it's still not an official build. It's not sanctioned by Sprint, HTC, Google, your principal or anybody else. And some things don't work, like 4G data, the cameras, MMS, and tethering (and it looks like it's still trying to roam on me). But it's Android 2.2. On the Evo 4G. And we just had to try it out.
We've got video after the break where we benchmark this port against Froyo on the Nexus One and Android 2.1 on the Motorola Droid. (Just like our previous test.) And it's all brought to you by the root and recovery of the Evo 4G, some quick cooking at Geek for Me, and your pals at Android Central. [Geek for Me via XDA Developers]
