Dropped iPhone 5, screen problems?

A few weeks ago, I dropped my iPhone 5 on concrete and the screen smashed. The damage wasn't too extreme. Anyway, today I'd been a *** to my mum and she took my phone off me. She got really pissed off and threw it at the floor (she's really over dramatic). I picked it up and part of the screen was smashed even more than before and there were 2 thick white vertical lines down the very right side of the screen. I gave her my phone and walked out the house. I just came back in and she hasn't said anything to me but my aunty said my phone still works. I'm not allowed it until Monday and I'm worried that the touch screens going to be unresponsive.

Is there a way to fix this screen or anything else I can do?

By the way, I live in the UK and this is my second iPhone since Christmas. I smashed my other one in March and my mum paid £180 for a new one so she won't get me another one, although its her fault

What router would suite a house like mine?

In my house (I share with 6 others), we have a total of 21 devices sometimes simultaneously using the wi-fi access from our BT Home Hub 2.
That's 7 laptops, 3 Xbox 360's, 5 Ipods, 2 Iphones, 1 Nexus, 1 3DS, 1 WII you and 1 TV.
As you can imagine it gets very laggy, but this has nothing to do with the provider or contract but the router itself.
As well as this, the biggest problem is the wi-fi drop out, which frequently occurs when the router essentially stops all wi-fi, and requires a reboot to work again because of the 12 or so connections using the wi-fi.
We're looking for something (ie. Router, access point etc.) that will help solve both the drop out problem caused by the amount of devices using the router, and the lag sometimes caused during online gaming.

Any advice?

How to cancel my orange contract easily?

I have been in an Orange contract since last april. I have been paying £20 a month to pay for a samsung galaxy ace and 100 minutes, unlimited texts and 100mb of internet and insurance. However, I feel like this is a rip off and have recently just purchased an iPhone 4.So no longer need insurance. I want to change to giff gaff because they have amazing deals on just a sim, seen as I unlocked the iphone! Is there any way that I can easily get out of the contract, like by saying I can't afford to pay the rest of it?
