Just saw this, sorry you're having problems...and you were so happy with it
The soft reset seems to be more than just pressing reset, I found after my last freeze:
While pressing reset with the stylus, you also keep the on/off switch pressed for a few seconds, then release both and press the on/off switch again. No chanting or dancing required. Sorry for the superfluous info if you've already done all that, it's just that I only found out recently that that's the way to do it.
If nothing else helps, ask your retailer to exchange it for a new one. You've only had it for a few days after all.
Good luck and let us know.
