Exactly how bad is it to drop your phone, specifically an iPhone 5s?

I got an iPhone 5s a few days ago and I want to be Really careful with it. Sadly today I was holding my phone while walking to my car in a parking lot and I had a handful of stuff and it accidentally fell.

I have one of those shock protector cases and I keep it in one of those wallet-type things, so no external damages were done, but I really hope there were no internal damages.

So what exactly could happen to your phone if you drop it, and do you think my phone is okay?

Estimated cost of monthly contract for iphone 6?

Hi

I'm debating whether to get the iphone 5s or to wait for the iphone 6.

When the iphone 5s first came out, how much was the monthly contract for it?

The current monthly contract for iphone 5s is £33 at the cheapest. I can't afford much more than that.

how much do you think the iphone 6 will be on a monthly contract, without an upfront cost?

No sound on my iPhone.LIFEPROOF?

Just went swimming in my pool it's like 5 feet deep. Went underwater with my lifeproof case on of course. It was very slow like it wouldn't register my fingers swiping through apps and typing I has to repeatedly press the letter. So i'm in my room now and just realized I have no sound on my phone anymore. I do t have a warranty for my phone but since this is lifeproofs fault do I still have to pay for a repair?

Is 250mb enough data for an iPhone?

There's usually Wi-Fi wherever I go and I wouldn't have to use my data too much. When I use it with my current phone, its usually in the car or at a basketball gym I'm at but most of the time its only for snapchat. Would snapchat use too much data in a month? And if I get close to the limit, I'm smart enough to not go over.

When you give APPLE a defective IPHON do they give you a reconditioned one back?

My IPHONE had a defect, still under warranty, so I took it to an Apple MAC store and after a few days they gave it back, supposedly repaired.

IPhone 5c Black Screen but still vibrates on charger?

Ok so I have an IPhone 5c and awhile ago my little sister chucked it at the hardwood floor in my house and the screen came out of the phone a little bit but it didn't effect how it worked or anything so i just left it. Then a few days ago i dropped it face up on linoleum in a classroom and now the screen is black. In the dark you can tell the screen still lights up a tiny bit but other than that nothing happens. I've tried holding down the lock button several times and holding down both the lock button and the home button at the same time. Nothing works. I've also tried plugging it into my computer and syncing it just in case i lose everything but i have no access to anything because my phone is locked with a pass code.
I've plugged it into its charger and it vibrates like its charging, but still nothing shows up on the screen. Is there any way I can fix this? Or am I going to have to get a new phone? Please and thank you to anyone who helps.
