Should a 13 year old have an iPhone?

[Randi]

I'm 13 and our family didn't buy Christmas presents yet! I was hoping to get an iPhone 5, or even a 4s (my mom's old one), but my parents (mom especially) firmly believe that a 13 year old shouldn't have an iPhone. I don't want to sound like a brat, but I get good grades and I've been wanting a new phone for a while. Right now, I have a prepaid LG Optimus One which was already an entry-level phone almost three years ago, and it's so buggy and lags forever.

I think that my parents' unwillingness to listen to my reasoning or negotiate (skip a Christmas present and buy it in the spring for my birthday) is a little unfair. Again, I don't want to sound like a brat but it kinda hurts seeing so many kids YOUNGER than me having these great phones while I'm stuck with an older device. I also wanted an iPhone because I'm going to be travelling to New York and Oregon with my school and I wanted a phone that I could take with me that would also work as a camera. Recently, I've found myself always having to borrow my parents' iPhones to take pictures, look things up, use apps like Instagram, and tweet.

One of the issues that my dad has of buying me an iPhone 5 is that he doesn't want me to have a better phone than my mom, who has a 4s. That WOULD be understandable, but the thing is that my mom doesn't care at all what kind of phone she has. She's honestly never been that type of person, so I'm confused about how this would make sense in our family.

TL;DR, do you think it would be alright for a 13 year old to have an iPhone?
