If you took the last OTA for the HTC EVO 4G, and have been wanting and waiting for a root method, you're now in luck. The fellas at Revolutionary have worked out the kinks and the EVO 4G with version 2.16.0001 Hboot is now included on their list of supported devices. You'll want to read everything carefully and make sure you understand it before you dive in, but it's a fairly easy procedure. And if you hit a snag, there's always help in the EVO 4G forums. Happy flashing!
