HTC will give you at least $100 for your old phone if you trade it in for the One and only
The company will also give you a $100 or more for your older handset if you want to trade it in for an HTC One. You have to register with HTC first, then get the One and only, sending poof of purchase along with your crummy old talkbox to the company in order to receive a Visa card in the mail. Sweet, and similar to the $300 trade-in campaign for the One X.
