Have you ever texted drunk? Taken a photo on the loo? Or sent a sexy text - what we believe young people call a 'sext' - to the wrong person?
Apparently most of you have - depending on where you live.
A study by the mobile network GiffGaff asked 10,000 people on its website about various mobile phone 'faux pas' and found that a surprising number had made at least one of these cardinal errors.
It's a fairly interesting study but, as ever, actual conclusions - about why, for instance, 91% of Liverpudlians had sent a text to the wrong person compared to 72% of people in Reading - are hard to draw.
We've attempted to make five absurd leaps of reasoning below. Let us know if you can think of any more. Otherwise - skip to the real data in the graphic.
- Only 58% of Windows Phone users have used their phone to settle an argument compared to 73% of iPhone users. Which means Windows users are 15% more likely to die alone.
- 42% of iPhone users haven't worked out you can reverse the camera and instead photograph themselves in the mirror
- Phone users in Merseyside are more likely to send regretable messages when drunk because they get drunk earlier in the evening, before their phone batteries run out
- RIM users eat twice as much cereal as Android and iPhone users
- Windows phone users 15% more likely to consume hotter dinners (based on time taken to photograph their meals)
