Where can I sell a broken iPhone 5?

So my iPhone 5 is completely broken. I went into the Apple store and they told me that my warranty has expired and everywhere else says they can't fix it (when I turn it on it comes up with a blue screen with a bunch of errors).
Does anybody know where I can get the highest price for a broken iPhone?

Lost my iphone in the cold outside?

I'm an idiot, had a rough night last night. Got dropped off at home last night, was completely locked out in the freezing weather. Phone was dead. And I end up on my neighbors couch because it was die, or go there. Woke up, no phone. Walked to my house, my phone is sitting in the driveway FROZEN.

I haven't charged it or tried to turn it on. It's a iphone 5.
I currently have it next to my heater. What should I do or when should I turn it on?!

Inserting Tesco SIM card in a locked O2 iPhone 5?

I want to buy an iPhone 5 second hand that is locked to O2. I've read off loads of forums that inserting a Tesco SIM card into a locked iPhone 5 WILL work. Can someone please confirm if this is true (past experience?) as I don't really want to use unlocking websites.

No sound coming from iphone 4s?

No sound is coming from my phone.
the only sound is siri and ringtones. When i go in settings to select a ringtone i can hear it.
Also the volume buttons don't work. Only when i'm on siri. Not when i'm on the music.

It doesn't work for anything. Apart from siri and ringtones?
Does anyone know why?
I've tried flicking the silence switch and that didn't work either.

Just like this person. The exact same thing.

I'm getting no sounds coming from it though. The ringer works, but all other sound is off unless the headphones are plugged in. This goes for recorded movies, music I purchased, youtube videos, the sound effects when I slide the login button. Everything is silent. I have restarted it a few times now, but to no avail. Even the sound buttons on the side do nothing; now they don't even bring up the sound volume overlay

Dropped my iphone into a bucket of watered down PVA?

I put my phone on a chair next to the bucket and it slipped of into the bucket. It was in there for about 2/3 seconds than i took the case of and dried it off. (It had a really big toy story alien case on)
Pva got into the headphone jack and charger bit and i got it out and it still charges and the headphones work in it.

I thought everything was ok then suddnly the sound stopped working with music and youtube. But it still works when i press down for siri? And i can't change the volume with the buttons? Only for siri. Not for the music or youtube?

What's happened please help me? I've only had it for like 3 weeks! My parents are going to kill me!

Is it ok to get iphone 5c rather than iphone 5?

I'm getting one after days, but my chance of getting 5c is higher than getting iphone 5 since it's cheaper, but i heard that it is really bad with the plastic body and it's look which seems to be made for kids
