How to stop being materialistic and jealous?

My girlfriend just got an iPhone 6s and I'm being irrationally jealous of it. I'm 18 and I still don't have a working phone. I play sports and I'm trying to go to college and play a sport so I really don't have time for a job and my parents don't believe in spending money on stuff like that. I know it's materialistic and stupid but I feel really jealous of her. I don't really know how to handle it.

Should I get 16 or 64 gigabytes?

I'm getting an iPhone 6s and I'm thinking of getting either 16 or 64 gigabytes. I take a lot of pictures and I will be downloading messenger apps like Whatsapp and Messenger. The only apps I will have are these, instagram, a couple picture editing apps, and maybe a couple games like flappy bird or something. Is 16 enough or should I upgrade to a 64 gigabyte phone? And a bonus question: Which color is better, silver or space grey?

SIM unlock a Japanese iPhone?

Just bought a iPhone 5 through a person to find out it is still locked. (yay) Apparently the carrier is soft bank, and so is mine. I put the SIM card from my broken phone into the one I bought to find that it is not valid. So I must get it unlocked. I heard it is expensive and I'm not trying to spend a fortune. I heard about some unlocking websites, but I wonder if any of you guys know how to unlock it at home? If not, what would be the cost to go to a carrier to unlock it?

Will Verizon replace my iPhone 6?

I have an iPhone 6 currently and I can't connect to my cellular data. I have made sure all of my settings are the same as my siblings and they are but it still won't let me connect but it will let my siblings connect and yes our bill is paid. When I go back into my cellular settings everything is turned off and it is really annoying. Everything was fine until I updated to iOS 9. There was also another update after iOS 9 to fix the cellular data but it didn't help at all. I didn't have this problem before the iOS 9 update so what should I do? Do you think Verizln will replace my phone with a new one if they can't figure out the problem?
