After failing to ship the HTC One according to the initial launch schedule, HTC has decided to offer potential buyers another extension for the HTC One trade-in program.

This is the second time HTC does this in a matter of days in order to cope with the HTC One shipping problems. Here’s what HTC told AndroidGuys:
HTC is thrilled with the positive response we have received to our $100 trade-up offer. Due to this, we are extending the offer for customers who purchase the HTC One by 4/26 and trade in their old device by 5/31. We are pleased to bring this offer to even more customers so they can upgrade to the HTC One at an amazing price.
HTC One buyers that register on the company’s website until April 4 and buy the device by April 26, will get some cash-back for their old handset.
Depending on the trade-in value, you’ll a pre-paid Visa gift card with at least $100 credit on it (perhaps more depending on the value of your trade-in) as long as you complete one more step by May 31. That’s mailing a copy of the proof of purchase of your new HTC One alongside the handset you’re trading-in for the new HTC smartphone.
Are you buying an HTC One this year? What handset will you trade-in?
