Sprint provide Hero over-the-air update 1.56.651.2
Those that are waiting for Android 2.0 on their Hero will take some peace in the following news, but will ultimately have to keep on waiting. Sprint have released an over the air (OTA) update for this device, but it is nothing to get excited about. The change to 1.56.651.2 is less of an upgrade as it is an update. Nonetheless, OTA roll-outs are always encouraging to see, and prove that carriers are dedicated to keeping their existing clients happy. The update itself is just under 3.6MB and should help improve your battery life, amoung other things. If you have yet to receive the update/upgrade, you can manually set the ball rolling by going to settings, then select About. Click System Updates and follow the onscreen prompts to Firmware Updates. Done.
