Android 2.1 for the Sprint Hero is rumored to be released on April 9th. Why wait when you can have it now (or the official test ROM)? The latest RUU from Sprint has been leaked by a member from the XDA.

Damageless from the XDA has released the official Android 2.1 test ROM for the Hero on Sprint. But this isn’t a simple flash update. Noobs do not attempt this or you may brick your phone. For those of you brave and skilled enough get the ROM from here. Being a test ROM, it already has root, follow the instructions listed and soon you will be enjoying all the goodies of Android 2.1. I’m sure an update.zip will be made from this soon.
