How to save for the iphone 5

Ok so hi. This year i'm getting a iphone from my parents (i'm 14 first phone! ) and we have no contract… So my parents and i were discussing phones and they said they would buy a phone for me that was $200 like my brothers, but i wanted the white iphone 5 (i sound spoiled lol) so I told them i would really really like it but they said that was a problem 1. Its 649 dollars! Btw we have no contract(not getting contract anytime soon lol) 2. I lose a lot of things and they think i will lose it and they don't want to pay for something that i'm going to lose (WHICH I'm NOT!) so yup thats all a big problem and i'm worried but then i found a solution! I will pay the extra amount while my parents pay for the 200 dollars of the iphone and i pay for the rest which is 450 dollars. Btw i'm broke and i have no clue how to save money. So please if you would be kind enough to tell me ways to save 450 dollars and any helpful suggestions to tell my parents how i'm responsible and ways i'm NOT Going to lose my iphone 5!
