Why do I not get treated equally?

I have two younger brothers one is 10 one is 12. I'm 14, I'm a a girl. I'm so confused. Why do I get treated differently? For example we got our report cards a while ago and my 12 year old brother got 3 F's and my 10 year old brother got C's and so on. My worst marks were B+'s.both my brothers got iPads and I got nothing. It was my birthday 3 months ago and I got money for my birthday so I told my mom I want to get an iPhone 5 with that money, and still today I didn't get that phone, whereas my brother has just asked my mom for a new phone and he will also get it for nothing. On his birthday he also got money and he went the same day and bought a pS3. I don't understand this. Any help?

Yeah, I hear you! Your brother's should not be rewarded for bad behavior, but they are. Your parents should not side with them and condone failure. 3 F's is no reason to reward, it's means to ground them. But, in passing, do calmly tell your parents you have done your best, even though they do not acknowledge that, but play favorites and it isn't fair. If they say "we expected you to get all A's". Just say, I did my best, didn't fail and have no want of ever deliberately doing that. But, you should not reward failure either. Say it in a calm voice to get your point across. When they see your maturity, they'll better understand they did the wrong thing. Good luck and I know how you feel because I've been there too.

They might just be more protective of you, its ok to ask them sometime and ask why you didn't get an iphone, they might not want to get a phone as that involves monthly costs where an ipad does not.
