The root, the root, the root is on fire! Well, not quite, but you just got another pretty splendiferous reason to hack your EVO: android-wifi-tether, an app doing exactly what its name suggests, has now been confirmed to support HTC's 4G-capable phone. There were apparently some compatibility issues at first, but those have now been ironed out and superuser-empowered folks have been successfully pairing the free app and supersonic phone since. Might as well jump on board with this one -- Google has already said Froyo's native ability to do this might be circumscribed by carriers, meaning Sprint's likely to package any official firmware upgrades in such a way as to keep you paying for hotspot capabilities. And who wants to do that?
