My parents are unfair?

Okay, before you think I'm a spoiled brat, please hear me out. First of all it's summer time, and my brother and I still have to go to sleep at 11:00. SUMMER TIME. It's because MY DAD AND STEP MOM have work and they don't ever trust us. My brother and I always try to convince our dad, and today, we asked him to consider extending our bedtime, but he got all pissed off and said "IT IS WHAT IT IS" Claiming that we'll make too much noise. HE NEVER GIVES US THE CHANCE IN THE FIRST PLACE. Another thing is that he doesn't allow us to have cellphones. My older brother is 15, turning 16 in a week, and HE STILL DOESN'T HAVE ONE. They say we have to show our responsibility, but then when we do, they say that we have to get our own jobs and pay for it ourselves! My mother (we don't live with her) was considering buying me a phone, and my dad was perfectly okay with it! She doesn't have as much money as my dad and step mom, so she wasn't able to, but I don't blame her. It's all about the price with them though! Not responsibility! They can afford to spend money on vacations abroad for themselves and redo the back patio, yet they can't pay for phones! What a bunch of crap! I know that some of you are thinking "They have the right to do what they want with their money!" but really think about where I'm coming from. The last thing is that I'm not allowed to have friends over when they aren't home. I don't really have people over, and If I could I would have only one or two at a time. Whenever my friends can indeed come over, they aren't allowed upstairs! My dad and step mom think we will go and fiddle or take stuff from their room! It's ridiculous! I prefer to not have them over at my house when we hang because we end up being secluded to one room! Whenever I visit another friend's house, their parents are very nice and trustful towards me. They make me feel like I'm welcome. If I were one of my friends visiting my house, I wouldn't feel too comfortable... I want to know what people think of this. Are they being reasonable? What can my brother and I do to convince them? Don't say prove our responsibility or talk to them about giving us a chance because we already tried that...
