How to charge iPhone 6 for the first time?

Can you switch iPhone 5c colors?

So I have a blue iPhone 5c and I would like a pink one. I got it like a while back (maybe a few months ago, around there) and I really would like a pink one… Is there anyways I can maybe trade it in or swap it? Do they let you do it? The phone is in perfect condition (no cracks on the screen, no scratches, etc…) Thanks.

How much should I sell my cracked iPhone 5s for?

So earlier today i cracked my 5s by picking my bookbag up from the table that my phone was on to move it to another table and my phone flung up in the air and landed face down on the ground. I have the T mobile plan and need to pay off my phone in order to get a six (no smart comments about how I shouldn't upgrade because I'm not what they call "careful" enough) I would fix the screen but don't want to spend that much if I'm planning on upgrading at a later date anywaysHow much should I sell my cracked iPhone 5s for - 1

Why does my singing sound bad?

So, I've been singing for 2 years now, and I recently got a microphone, an amp with a headphone input, and a pair of Audio Technica ATH-M50x Professional Studio Monitor Headphones. I plug the headphones into the amp, and sing into the microphone, and I sound really good. On pitch a majority of the time, and when I'm not, I fix my pitch and I sound amazing for the rest of the song when I sing. I sang the other day in front of a couple of people, and they told me I had that "raw natural talent." Problem is, when I use my iPhone (4) or my windows 8 ASUS laptop to record myself singing, I sound bad. Not bad as in nasally, or off pitch. Just like, really flat, bland, and like I'm not singing at all. However, when I sing into the mic with my headphones on, I sound really really good. I have full resonance, I don't sound flat or bland, and I even amazed myself with how I sounded. I'm not entirely sure if it's the laptop/phone's microphone's fault, or if it's mine. I'm really confused and I'm starting to get discouraged because this isn't the first time that this has happened before. I've always wanted a mic because I'm a lead vocalist/back up vocalist in my band, so it was a necessity, and the headphones stop the vibrations going in my head so I can hear myself and how my voice is exactly, which is pretty cool. So I personally think it's the laptop/phone's fault, but I wanted to see what everyone else thought about this. I DO smoke, but not while singing. What do y'all think?

Added (1). I just straight up record with my phone's camera, or my laptop's webcam. No effects or anything. Just the regular settings of the webcam & the camera's microphone & quality

IPhone 4S, issues with restoring?

I decided to use my iPhone 4S again after it being put in a draw for years and I have completely forgot the passcode for it. I've plugged it into the computer (it has never been connected to this computer before) and it asks me to allow access but I can't because I can't get into the iPhone. When I put it into DFU mode, it comes up with the iTunes error 3194 and after using TinyUmbrella it comes up with the iTunes error 11. I can't use the iPhone at all now because I can't restore it and I can't remember what software it is running. I'm starting to lose my temper with it so please, what can I do?
