Switched from iPhone to Android, still getting iMessages on iPhone?

Just recently switched from an iPhone 4S to a HTC One Google Edition. For whatever reason, my number is still linked to my phone, so when other iPhone users try to text me, it picks up as me owning an iPhone and sends it to my old iPhone. I would like to keep iMessage on my old iPhone but through my email only, not through my phone number if possible.

Added (1). I wish it was my through email, but its not. I tested myself, if I use an iPhone to send a message to my number, it defaults to iMessage.

Added (2). Yeah you're not allowed to deselect your phone number on an iPhone. You can on an iPod and iPad but not iPhone

Use AT&T iPhone 4S on T-Mobile network?

Let's say I get a phone upgrade on my AT&T contract next month, and I get an iPhone 4S. My contract is up in December and I don't plan on renewing. Could I take my iPhone, have them "unlock" it at the AT&T store because I've been a long time customer in good standing, and bring it to T-Mobile and use it on their network? If so, would it be able to pick up 4G speeds, or would it just be 3G? I don't have T-Mo LTE in my city yet but I'm really sold on the unlimited data, talk and text plan.

Why does my iPhone reflect all my pictures?

Whenever I take a picture with the iPhone front camera (no apps) it reflects it. For example, if I'm leaning to the left, in the picture it will make me leaning to the right and vice versa. Why is this and how do I stop it

IPhone dropped. Unique issue

I have had no problems with damage to my iPhone 4S but I recently dropped it on pavement and my music stopped then the screen slowly faded to black and shut off. I gave it a half a minute then powered it on and now it's perfectly fine. Exactly as it left off, except the music wasn't playing. Is there anything wrong anymore with my phone? Why did it fade out then shut off? Should I be scared for the next time I drop it?

Is this little shock from an outlet something to worry about?

I was trying to plug in an iphone charger. I was wiggling the plug around in front of the outlet. My fingers were touching both teh plug and the outlet, and I got a little shock that didn't really hurt, mostly just surprised me. The shock traveled about halfway up my elbow (probably 4 inches above my wrist.) Is this something to worry about?
I think I'm completely fine, but I'm just making sure. It was my left hand. I mean, if I can type, I'm good, right?

Why can't I take pictures with my iPhone 4?

I only have 170 pictures and 30 songs. And two pages of apps. That's it. And all of a sudden, my phone won't let me take pictures, even when a few weeks ago I was able to take pictures when I had 300 pictures. I've tried resetting and that didn't work.
