What's your Priority Moment? A world first...

It’s Friday, it’s the 16th of March and we’d like you to come play what we think is a world first – an interactive story told on Twitter.

If you’re on Twitter you may have seen a new promoted trend this morning – #MyPriorityMoment. This is the starting point of our interactive story – what we think is a world first for Twitter. It’s a story that lets you live through an ordinary day and see the difference Priority Moments, our app that gives O2 customers exclusive offers from a huge range of stores, can make to your day. Every day sees us make choices, but some moments are extra special. Priority Moments, if you will. It’s also a story that can win you an Xperia S by Sony if you play it well…

If you’re not sure where to start, visit https://twitter.com/#!/search/realtime/myprioritymoment. At the top you’ll see a tweet from O2 that asks you a question – click one of the hashtag choices and you’re on your way! Remember Choose Your Own Adventure Books? That, but for the 21st century…

Certain choices (made by clicking hashtags in each subsequent tweet) will see you get to the end of the day and see instructions on what to do to win a Sony Xperia S – we’re giving one away every three hours so you’ve got plenty of chances to win! Either way we’d love you to tell us what you think of the game – tweet us @O2 with #MyPriorityMoment and let us know how you got on – enjoy the game!

There are a few terms and conditions for this competition – we’ve inserted them below. They’re a bit long though, sorry…
