Resetting an iphone, i want to do it right

So once before my brother had an iphone and was giving it to someone else and he reset it through the original settings but what happened was he completely erased everything, EVEN SIRI! I don't know how but he did.

I'm giving away my iphone and i want to make sure i do it right to sell. Any help would be great.

Added (1). And would really be nice is if someone can tell me how do i get rid of pictures thats on the phone that were synced from my laptop when i plugged it in. Will they all erase when i reset the phone?

Fruit Ninja Free suddenly turns to a full version on iOS?

This is not actually a problem but I'm curious about it. I have had Fruit Ninja Free installed a long ago, and only the Classic game mode worked as it was only a free version.

But after a recent reinstall of the app from a backup (after restoring my iPhone), suddenly all game modes work just like the full version but it still reads Fruit Ninja Free. What do you think happened (I'm not complaining by the way, just curious if this was some glitch).

IPhone 4 is frozen on Apple screen. What do I do?

It's stuck on the screen with the apple.
It's plugged into my computer but it doesn't change.
I can't restore it because I have to have the iTunes screen show that the phone is plugged in.
I've held the sleep/home button down together and it changes the screen to show that the phone needs to be charged.
When I plug it back into the charger, it does the same thing all over again.

Verizon iPhone 4S with no sim card slot?

I have a Verizon iPhone 4S that I'm selling that has no sim card slot in the side. But apparently there's no such thing as a Verizon 4S that doesn't have a sim slot. I 100% know that it's a 4S, because it has the antenna in the right place, it has siri, and I went to the verizon store and bought it straight from them, brand new. What's the deal?

Added (1). But everyone keeps saying that every iPhone 4S from Verizon has a sim card slot. Why doesn't mine?

Is there anyway to stop, bypass, or trick T Mobile Family Where?

I'm 18 and since I started college, I've been going out a lot more and partying and all those things normal college kids do. Well my dad being the overprotective and worried person he is decided to start tracking me with T mobile Family Where (without telling me, I only know because T Mobile sends a text letting me know I'm being tracked). I know that it uses cell phone towers to give an estimate of my location, so my question is; is it possible to stop this besides turning off my phone and removing the battery? I have a jailbroken iPhone 4, so if there are any cydia apps or tweaks that could help, please share!

How much will it cost me to live?

Hi! Recently I have made the decision that after I graduate high school I will move in with my dad. Knowing my mom (who supports me 99% financially) will more than likely cut me off. She pays for my car insurance, phone, groceries, etc.

I'm curious as to how much I need to make each month to pay for myself.
phone: preferably an iphone on with att or verizon
Car: I'm 17, I turn 18 in August, I have a 2012 nissan versa, I have never wrecked or gotten a speeding ticket
groceries: I will morebghan likely have to buy these myself Bc me and my dad have totally differnet eating habits. I like fruits and vegetables etc
College: I have my tuition laid for but I still have to pay for books, parking, and I'm living at home

I probably won't move until mid-summee until I have saved up enough money from my 3 jobs

Why is my iPhone 5s home button making a weird noise?

I know that its a button and that its supposed to click, and it did in the beginning. My phone is less than 4 months old, and recently when pushing the button it makes a cracking or crunching noise. Even if I just push down lightly, like to use the finger scanner it makes the crunching/cracking noise?

I know it didn't make this noise in the beginning? Is this normal?

Thanks!

Added (1). Apple always has a 1 year warranty right? So, would my phone still be covered?

Is the 300mb data plan for AT&T enough data for me?

So I'm thinking about getting a iphone 5s 16gb with the 2 year contract and I'm thinking about getting the 300mb plan and I'm wondering if that is enough data for me and I spend most of my time at my house and my house has Wi-Fi and so does my school and I don't use Facebook, Instagram, snapchat, twitter or any other app like that and I won't be downloading a lot of apps because I have all my apps and music on my ipod 5th generation and will the 300mb plan be enough data for me?
