HTC and Marvel are given away limited edition HTC One (M8) smartphones with the S.H.I.E.L.D. logo emblazoned on the back as part of a tie-in with the Captain America: The Winter Solidier movie.

Entrants are asked to submit a Captain America-themed selfie on Twitter with the hashtag #superselfie or on HTC USA or HTC Canada's Facebook page (depending on region). Unfortunately, UK fans are not able to enter.

It is not likely that the special handset will ever be sold, but those who are unlucky in their attempts to win one (or are from countries other than the States or Canada) can download wallpapers for their devices.

The limited edition S.H.I.E.L.D. HTC One (M8) phones are the same gunmetal grey as the traditional version but with the logo etched into the back. There are 10 US phones available in the giveaway and four for Canada. Contestants can only enter once per day and you can already see some of the attempts on Facebook. Stiff competition we feel with the amount of cosplayers out there.
