Sprint has just announced via its official forums that a maintenance update for HTC Hero owners will begin to rollout today. Bringing in a few fixes, it’s a welcome update, especially when we won’t be seeing anything beyond 2.1 for the device.

With just a few fixes, the update includes the following:

• Correct a non-customer impacting issue (device diagnostics)
• MMS issue with contact number format
• Updated Sprint Zone application

To update your device:
• Go to All Applications
• Tap Settings > About Phone > System Updates > HTC Software Update
• Select Check Now
• Follow the on-screen instructions to download the update

The update will take about 5-10 minutes to download, followed by another 5-10 minutes to install and will bring your current software up to 2.32.651.2.
