Today there's been released an HTC Hero Android 2.1 update. It's not an official release, the owners have been waiting for Sprint to release it on the market. Sure, not being an official version means you can update you HTC Hero using it, but there's not any assurance it will not root your smartphone. There is actually no way to know if this version will also be an official one in the future, but you can update your operating system if you just can't wait any longer.

You can download the update from here, but I advise you again. It's an update at your own risk, because this is not a version from any carrier.
