Does this story seem plausible?

My friend said his cousin who is 16 years old, made this iphone app (cost him very little to make), got it approved by the app store, and made over a million dollars in the following 6 months. Does this make sense, that a kid could become a millionaire in 6 months like that, with the whole process of app development?

Cracked screen and water in screen? Apple?

IPhone 5s fell on ice and there's a few cracks and there are bubbles (water) below the crack. Will Apple still repair screen for 130$ even though water damage is there?

Why does my iPhone 5s never have storage?

My iPhone 5s has, within the past year, been causing me serious issues in terms of storage. It currently still has iOS 7, which I recently tried to update because I figured maybe that was contributing, but the update would never complete. Anyway, it is constantly giving me storage messages, saying it has no room to back up, etc, etc. I've tried to clear space. I only have three apps on my phone at this point (deletable ones, I mean--there are of course the apps that you can't delete). I have only twelve pictures, only ten songs, etc. I've removed all my pictures in the past and nothing has changed. IIm losing my mind with this because it is making it so that I can't take photos, can't download apps, can't send photos etc. I've tried googling it, but can't find anything that helps. If no one on here can help, my next stop is probably the apple store. Does any one know how to fix this?

Dropped my iPhone 6 in sink but still works?

I dropped my iphone 6 in a sink with barely any water in it. I grabbed it immediately and dried it off with a rag. It works completely fine and even sounds work and it still charges right. The only problem is. It says "accessory may not be supported" when I take it off the charger? I turned my phone off for the time being, what should I do?

Can I buy an iphone 6 without contract and use my old sim?

So I currently own an iphone 5 with a contract from O2. IIm long over due for an upgrade but can't get one since my phone contract was made under my guardian s name, whom I no longer speak to(though this is another problem).
Anyway, IIm currently in Korea and my phone has practically given up after it's long service: data full no matter how much things I delete, screen freeze and crash, and sometimes turns itself off etc.
If I buy an iphone 6 here and inset my old sim from my current iphone 5, will it work fine and will O2 be ok with this?
