Removing acrylic paint off an iPhone 5 Otter Box case?

The title speaks for itself but I also put clear finger nail polish so it won't chip off so easily. But now I'm bored with the design and wanna change it. What's an easy way to remove it without damaging the case?

Can I still get my iPhone 4s fixed with applecare after i've upgraded?

My iPhone 4s was giving me major issues and I live over an hour away from an apple store with everything going on I just didn't have a chance to schedule an appt and get it fixed. Anyways I had an early upgrade and upgraded to the 5s because my 4s wasn't working and the best buy mobile is right down the street, we have one of those lol. Can I still go get it fixed though? Even though its not hooked up. I would like to use it for an iPod and would like to put it on my plan in a few months once my boyfriends contracts up to avoid another contract. I can't seem to find out and whenever I try calling the apple store I can't get through! I'm actually going to be in the same city as the apple store this weekend so I could potentially get it fixed. I did pay the money for the applecare just like on my iPad, so I feel like I should be able to but anybody who knows for sure please let me know. Thank you!

Added (1). p.s. My applecare is still valid I checked it with the serial number and everything.

How to keep my iPhone 5 from going to sleep when a video is being played?

My iPhone 5 is running the latest version of iOS 7.
Lately, I've been noticing that when I'm following a workout video, it goes to sleep after a while.
This has never happened to me before, and I've had this phone for more than a year.
It's very annoying when your phone just goes to sleep when you're trying to workout.
I use apps to workout, but it's not just one particular app that this has been occurring in.
Can someone please tell me how to fix this please?

Should i take my iPhone to reading festival?

I really would like to take loads of pictures with my phone because that is all i ever take pictures with but loads of people tell me it will probably get stolen or damaged? How else would i take photos? Taking an old phone would solve the communication problem but not the photo problem, taking a digital camera is just as risky as taking an iPhone, and i won't be able to take too many good photos on a disposable camera? What should i do:/
