I am on my second Hero for the same exact reason! I don't know what causes it but my home and i believe search button stopped working on mine.

Got it replaces and haven't had a problem since. I honestly think it has to do with handcent for some reason when it has that pop up notification my phone would bog out and then the home button wouldn't work. Just a wild guess from my experience but probably wrong :X

Hopefully you can figure it out.
