It wasn't quite Android 2.0, but the recent firmware update released to the Sprint HTC Hero did have some bug fixes that are certainly worthwhile. Here's the official change log:

HTC Hero Software Enhancement SW 1.56.651.2 provides feature updates and enhancements to address the following:

  • Improvement to camera picture quality
  • DST (Daylight Savings Time) issue addressed
  • Unable to receive SMS due to full memory
  • Memory leak when Bluetooth is in connecting state
  • 3.5mm mono when not using headset with mic
  • Dialer application causing excess battery draw

Important note:  Dedicated Mute/Speaker buttons have been added to the Talk screen
