SOOOOOOOO not fair but its about an iphone!!!!! Will give 10 points BEST answer?

Ok i'm trying to sell my BlackJack 2 to get an iphone. My mom says that if i cant come up with a good reason to get an iphone i cant sell my BlackJack 2. I bought the BlackJack 2 with my own birthday money. And i was hoping you could give me some reasons why it would be better and good than my BlackJack 2. Something that it can do that my BlackJack 2 cant do. Also i do not have internet on my plan but what else could i do with it that i cant do with my blackjack 2 without the internet. Something to convince my mom and give her a good reason
