Is 8gb enough for an iPhone? - 2

I'm getting an iPhone 4 (old, I know) and I was wondering is 8gb is enough cos the iPhone 4 only comes in 8gb now. I won't have a lot of music… About 200 or less but I want a few apps like 20/30 and I don't save videos on phones.that's what YouTube is for. What do you think? Is it enough for me? Or should I go with the 4s?

What to do to fix my iphone 5 if its not responding to touch?

I have an iphone 5, it's pretty new less then a year old.yesterday i tried unlocking it but it wouldnt respond to touch so i tried turning it on and off. When i did it just went from the apple logo to black to black and gray stripes. I decided to leave it alone for a while and it worked normally.
yesterday night i put an alarm clock but i didn't wake up, i'm not sure if it was because i just didn't hear it or if the phone stopped working. I tried unlocking it but it still didn't respond but i did get whatsapp messages. I tried doing what i did yesterday and the same thing happened with it being just apple logo, stripes and black for a while. It just turned back on and its not responding to touch again. I know for sure that it didn't touch water or fall or anything, at least not on my watch and it still charges.

Am I spoiled or are these people spoiled?

My parents always have told me that I'm incredibly spoiled. I have always went along with it, believed them, and went with it, and I'm very grateful to my parents for providing me all of these things. To be honest, compared to many people, I'm spoiled because:

-I have crab or lobster on my birthday every year
-My family and I go to the beach once every year (sometimes twice but not that often)
-I eat sushi about every other week
-I wear designer jeans
-I have a pretty decent amount of makeup from expensive brands like NARS and Lancome, but I have nowhere as much as the beauty gurus these days
-I have a pretty large room
-I get in the area of 20 gifts for Christmas every year (only child rewards)
- I have a jewelry mannequin that is smothered with jewelry
-I have an iPhone, but it's only the 3gs
-I have a computer all to my own
-I have two televisions in my house
-I have my very own camera and video camera

You get what I'm saying. Most people would consider me spoiled, and most of the time I do as well. This is where it gets complicated. I go on YouTube, and I watch videos with beauty gurus and supposedly normal kids who are my age. They have much more things than me, they have televisions in their room, laptops, and iPads, and they get to go shopping every week- I only get to go shopping every month. Is it that I'm spoiled or are they spoiled? Also, is it both? Am I just spoiled and they are just Really spoiled?
