Bringing my iphone to a apple store?

I have a quick question. So my iphone 5 won't charge at all, i thought it was my charger so i borrowed a friends and now the darn thing won't charge a bit. I was wondering if i brought it into a apple store would they just give me a new one? And this is a random question but could you get a different color iphone i was just wondering thanks in advance.

Do the Iphone 5 headphones work with the Dualshock 4?

I'm getting a PS4 soon with my brother soon. We will both need a controller and headset. So my question is. Do individual bought controllers come with a headset, and do the IPhone 5 headphones work? I know the PS4 comes with a Mono headset.

Tmobile switching to iphone, what do i need to do?

My Tmobile samsung galaxy s2 broke and my friend is giving me her old iphone 5. What do I need to do to get it to work with my sim card and memory etc.
It's not jailbroken or anything. Do I need to do that? And do I need to notify my provider or anything?

My iPhone 4S sound is not working

Okay so no sounds will work with without headphones in, I've researched it and still can't solve the fault but it seems to be a common problem.

I've cleaned out the charging port, the audio port. I've reset my phone, reset factory settings etc I've left it til it run out of battery then charged it up but still not joy. I've inserted the headphones in and out several times and flickered with the silent button but still nothing!

It seems sounds only work when I plug headphones.

Is there any other ways to solve this? Really frustrating!

Why won't Apple ever create a device that is sd card compatible?

I don't get it. Apple products like the iPod & iPhone never come with extra SD card storage. Its quite unfair of them cause they force you to use their Cloud Wi-Fi storage service & I don't want to. Other leading organisations like Samsung offer expandable storage with SD cards in their galaxy range.

Why are apple so reluctant to make iPods & iPhones that can take SD cards?

What electronic device is best for kids?

With Christmas coming up, I'm faced again with the question of what to get the kids (3, 5, 8 and 10.) Rather than toys that clutter up the house, I'm debating electronic devices. But there are so many! Nabi, tablets, Chromebooks, Ipads, Ipods, Nook, Kindle…

I can't find a good source that compares these things according to costs. The main question is what requires a monthly fee and what doesn't? I know an iphone and an ipad must be used with a cell phone provider. What about an ipod touch? A Nook? What devices can be used with my current Wi-Fi in my house without an extra cost?

They want:
A device that gets internet
Prefer a device that is handheld or portable

I want:
Durability (otterboxes may be also bought this year!)
low cost/ no monthly fee if possible
Potential for growth (not something that they will get tired of/outgrow in a year)
