Win a HTC One with #O2TubeWifi!

Reckon you know London?

To celebrate free London Underground WiFi for O2 customers, we’re giving our Twitter followers the chance to win a brand new HTC One by working out and tweeting us with which tube station we’re at. We’ve already given away a brand new Sony Xperia Z to a lucky tweeter with #O2TubePuns, now it’s your chance.

You’ll need cunning knowledge of London’s tube stations to win. All you have to do is tweet @O2 using the hashtag #O2TubeWifi and tell us what station we’re at in our Vine video to be in with a chance of winning.  Full terms and conditions can be found here.

Good luck and happy tweeting!
