In a scary series of emails sent out from HTC today, HTC President Jason MacKenzie explained to the perspective HTC One buyers that their phones may not be here quite as soon as many thought. The email, which was sent to all that preregistered on HTC’s website, stated that the One would be available to North American at the end of April. This is a full month after the date that many expected to receive their new devices. Even T-Mobile’s website states that to receive the trade-in value for your old phone for purchasing the new HTC One, your purchase must be completed by March, 31. There has been no word if T-Mobile and the other carriers will extend this promotion or not.
