IPhone 4 not responding to touch! What do I do?

So I was on my iPhone yesterday, and I was messing with the finger gestures things that is on assistive touch. All of a sudden, the iPhone doesn't respond to touch. At all. It turns off on its own, and comes back on, and now its stuck on the lock screen just joking with me telling me to slide to unlock.
I looked it up online to see how to fix this mess and I read to turn it off (by holding down the lock button, and home button for however so many seconds) and turn it back on, so it could kinda reset it, but the thing is that I'm using assistive touch because the lock button on top is stuck and does not work.
. And to make things worse the alarm keeps going off on my phone and the only way to mute it is by pressing on any of the volume buttons, but that only helps for about 10 minutes. So I'm having the alarm constantly going off. Super annoying.
I'm struggling with this iPhone 4!
& if you could tell me a way to fix the lock button problem, I would greatly appreciate it.
My phone is out of warranty.

--Thank you!

How to disconnect an unwanted Wi-Fi user, using my iPhone 4?

I have a home Wi-Fi network that I share with my family but I use the Wi-Fi for my iPhone but I'd like to know of theirs a way to disconnect unwanted Wi-Fi users with my iPhone 4. The reason their unwanted is because their usually my brothers friends that come over and use my Wi-Fi but since I don't have a computer and I do almost everything off my phone I'm curiouser to know if theirs an app of some sort or a process I can use to kick off my brothers friends from my Wi-Fi. Their using up a lot of bandwidth and lagging my Internet speed. If possible on android I'd like to know the app or process on doing it as well.

How to retrieve a list from the notes app on an iphone?

I accidentally deleted a list off of my "notes" app on my iphone. I got a new phone and was unaware that if I deleted the note off of my old phone that it would delete it all together, even on my new iphone. Anyone know how to get this information back? Any help would be greatly appreciated.

What happens if I take my jailbroken iPhone to the AT&T store?

My dad wants to go get a new iPhone4 because he is gonna give his old one to his nephew… But the current one is jailbroken-by me, so what happens if the people see that it's jailbroken?

Added (1). Btw I want to keep my old iPhone, so I don't care if AT&T doesn't want it. I'm just asking if they're gonna say that i'm violating their contract or whatnot just cause i jailbroke it.
