Now we are not sure if Sprint is going to release an Android 2.1 update for HTC Hero and Moment yet, even when we know that a Sprint Rep confirmed the March 26th release through a voice message.
If you are too anxious and can’t wait for the Android 2.1 update for your HTC Hero, a XDA forum member has release an Eclair 2.1 ROM for GSM based HTC Hero.
The Eclair 2.1 ROM brings lots of features which are part of the latest Android OS including Live wallpapers.
If you want to update your HTC Hero ROM, head over to this post on the XDA Forums and download the ROM. Make sure to follow the exact instructions to root your room and flash it. And yes, this goes without saying that you need to make backups before you do anything with your phone.
