If you live in the US and you're sick of your old smartphone, HTC would be happy to help you with that: if you buy an HTC One at any time between today and May 5th and send your old phone and proof of purchase to HTC by May 31st, the company will give you a Visa prepaid gift card of $100 or your phone's trade-in value, whichever is greater.

The most that HTC will give you is $375 in exchange for certain iPhone 5 models. However, as long as you have an eligible phone that still works, you can get at least $100 for it—HTC will give you that much for everything from the first-generation iPhone to the ill-fated Dell Streak. If you can find your phone on this list, input the promo code HTC100 to find out what HTC will give you for it.

As well-reviewed as the One has generally been, this promotion is indicative of HTC's current market position. The company's sales and profits have been backsliding for a little over a year now, and heavily advertised juggernauts like the Galaxy S 4 are reportedly making it difficult for HTC to get all the parts it needs for its handsets.

Our full review of the HTC One will be posted on Saturday morning, in plenty of time to help you make the decision if you're both tired of your old phone and on the fence about the One.
