Well, the Android 2.1 for Samsung Moment is out by Sprint today, but what about the Sprint Hero? Sprint didn’t launch the 2.1 officially, but the leaked version is out, the update is assigned with release keys, so you will lose your root, so be careful.
If you have two or three Hero’s, then you can try it on one of them, but do it at your own risk.
You can download the file from here, and if you try it tell us how it goes!
