Just switched from PC to Mac - tutorials?

I have an iPad, iPhone and iPod and when my PC died recently I decided I may as well get the whole set. So I have now changed to a MacBook.

Does anyone know of any online tutorials that will help me in getting use to the different system and functions?

Using my iphone on Wi-Fi in Canada (I'm from the US)?

So I have an iPhone, and I want to be able to use it in Canada. I would only be using it in a Wi-Fi area, so that I can access instagram and facebook and things, not calling or texting or anything.
What kinda of things can I turn off so I don't have messages and calls coming through, as well as data accidentally coming through?
Also, will I get roaming charges for using data in Canada (like internet, not calling) (I have AT&T)?

Why won't my iphone connect to my home Wi-Fi?

I have an iphone 4 and whenever i try to connect it to my home Wi-Fi it says 'unable to join network'. On my parents' iphone the Wi-Fi works fine. I also have the same problem with my laptop. I can go to another Wi-Fi hotspot and it will work fine but with my laptop and my phone it never works. I've tried restarting my phone and the router already. How can i fix this?

What iPhone 4S plan should I get?

Hopefully you could help out. Thanks in advanced.

My father and mom are currently on a Verizon plan. They agreed to buying me the new iPhone 4S, but with the iPhone 5 coming out soon, hopefully will the price go down? I'm not interested in buying the 5, however.

My father has a smartphone and my mother has a basic phone. I'm not quite sure what plan they are currently on, but we were thinking of adding me on to a family plan. I do currently own an iPod Touch 3Gen, and I don't use a lot on it, I have roughly 30 songs on it, and I might add a movie on it once or twice, but I checked with only my songs on, and I have a few apps, I currently have 6.1 GBs free on it. With that in mind, what would be the best data plan for all of us, myself included? Keep in mind I do want to use Siri and Siri requires internet.
What would be the monthly cost?

Shaking, blurred vision, dizziness?

Ever since Tuesday, I haven't been able to stop shaking, most noticeably in my hands. It's not even slightly shaking. It's horrible shaking, ex.: I was trying to do my homework in study hall today, and I was using the calculator on my iphone, but I could hardly type, I was shaking so much.
But anyways, I also get occasionally dizzy. Like after I spent a day at an amusement park riding rides, like you still feel like you're on one. And when I sit up, I'm dizzy.
Today I was heading to first period, and my vision was slightly blurred. I thought it was just something in my eye, but I kept blinking, and trying to get whatever was in there out with my finger, but there was nothing, and the blurriness remained.
Any idea as to what is going on? Could it just be stress? (I just recently moved to a new state, and Tuesday was the first day of school.)

How to activate Siri on iphone4S?

I have an iphone 4S but Siri does not show up on general settings? I've tried resetting the phone but the home button doesn't turn on Siri. And yes, i'm sure it's a 4S!

My iPhone keeps making a funny noise?

It's sort of lile a 'ping' sound effect, and it happens about 2-3 times a day but its never at the same times. Some days it doesn't even make the noise (RELIEF! Lol) It's so random, and I'm always terrified when it happens. I think it's trying to tell me it's overheatin or something, so I've sent it to my local Apple expert. I just want to know what other people think of it before I get it back.

How to remove an icover case from the iphone 4?

I just got a new iphone case and It WON't come off… Not that i need it to or anything but I like to be able to easily remove cases just in case I accidentally drop it, I can remove the case and see what the damage is. It's a sparkly blue case. I got it at 5 below below. The brand is icover i believe… It's a two piece that snaps together, very snug fit over my phone… I don't wanna remove it if it's gonna damage the case
