Look,
I'm 17 and I've been stuck with a "dumbphone" since I was 13. It has sucked really bad all up until now.
I used to be like you, a lot like you. I had to have every new gadget that came out... first I had to have a mac, then the iPod touch, then the iPhone, and so on and so forth.
There's a key reason as to why your parents aren't letting you use "your" money that you have in the bank. And that is because it's not really yours. The reason you have that 3k in there is so that your parents can say they gave you some cash, but you won't be allowed to use that cash until college- at which point every little penny of that 3 grand is going to be spent on school.
Now, I know it sucks. Because I want an iPhone too, I also want a MacBook Pro, and hell- even an iPad! But the truth is, at our age all of those electronics are irrelevant- you and I both know that that's the unfortunate truth.
You'll come to realize in the long run though that at our age the thing you want most isn't going to be some electronic... it's going to be a car. And now if you think that $200 you are saving for a phone is a lot imagine dropping $7,500 on a used car. If I were you kid, start saving and get a job.
I know at 14 it's harder to come by a job where you will get good hours so neighborhood jobs are good for the time being. 15 will open you up to a lot more as well, such as your local grocery store.
All I'm saying is, is that you don't want to get caught in this game of always keeping the newest and best electronics. Because if your parents aren't paying for your car you might want to start saving now because come 16 you're going to forget all about these electronics around you.
It's your money, do what you want.
That's my word of advice.
