Should I take my iphone 5 to Leeds fest?

I'm totally torn yes I know it's a risk but I will have it with me 24/7 and It'll be on a wrist strap so I won't drop it I just really need something to take good photos with and I figured my phone would be the best option.

Yes you should. It will get ruined but then you can get yourself a proper phone like the HTC one

When I worked in a phone shop a girl came in and she'd had a 1000 pound phone bill because she'd lost her phone at Leeds and whoever found it called loads of numbers in Nigeria.

So I'd take an old phone, but as the other poster says if you lose it you can get a better phone.

I'm off to the leeds fest I wouldn't bring it, it could get broke or anything just bring something else

I wouldn't! I have an iPhone 4 and i'm just taking an old blackberry from a couple years ago! I know you say you'd take precautions but you can never be too careful, and you'd regret it if you lost it, had it stolen or damaged it in anyway!
If possible take an old phone that still takes decent photos, or take an old camera that you maybe wouldnt mind losing? I'm taking a little digi camera that I bought for about 50 quid, i'd rather lose that than my phone!

Buy a cheap PAYG phone.
