Nokia 6682 / 6681

Well, I'm on my third cingular edition of this phone in three months due to it locking up and not recognizing the SIM card. The latest is starting to show signs it will do the same, like freezing and requiring a restart. I'm quite annoyed with this phone and ready to have cingular replace it with something else. Is there any sure fire way to "brick" this thing already, I've run out of patience.
