Iphone 4 won't turn on after IOS 7?

I download the I0S 7 update about 4 days ago, today I woke up and my iphone won't turn on, I plugged it in for 4 hours still nothing, I even checked to see if the charger will charger my dads phone and it worked.

MY INTERNET CONNECTION BECOMES LIMITED EVERY NIGHT?

So for the last few weeks since we got a new router from our isp at around 9.30-10pm the internet connection (Wi-Fi and wired) becomes limited on my laptop and. The router is on with all lights flashing, but the connection for some reason becomes limited. My iphone connects to the net at night every now and then usually after this happens but my ps3 online disconnects and says there's a DNS error every time i try to log back in. Any idea what it could be and how to fix it? Thanks it bugs me i can't browse the net on my laptop and ps3 at night. Also the connection works perfectly fine and returns back to normal in the morning.

Which color of iPhone 5c should I get?

I originally wanted a black 5 but there aren't any on the east coast so I decided to get a blue 5c. After looking at the cases, I'm starting to have second thoughts. I'm pretty picky and all of the cases I like clash with the blue so I would pretty much be stuck with a clear or black case. So then I decided I wanted to get a white one, but I think it looks terrible without a case and I've started to like the green as well. Here are a couple of the cases I'm thinking of getting:
(Navy) http://www.amazon.com/...00E8WE28W/
(Mint Green) http://www.amazon.com/...00E7WG8US/

And the front of the phone will be black
Also I heard rumors about a black 5c and I'm not sure if they're true/would be available?
Thanks

Apps that download music straight to iPhone?

Are there any apps out there that you can download music from the app and it will show up in your iTunes music on your iPhone without using a computer? Thanks for your help! The only reason I'm asking is because buying 10 albums in iTunes is a bit expensive.
