Did the hard reset the phone and loaded up handcent as the first app. Let's see how that goes.

Edit: Saw your post after I posted mine. Yea, go ahead and exchange it. If you don't mind me asking, what does your logo say on the back? HTC or by Google? I'm on my second Hero and one that's by Google has been awesome to me. No issues with memory leak and 100% wake time as of yet. (knocking on wood)
