How to convince my parent for an Iphone?

Ok so I got a flip phone for Christmas. I know it wasn't that long ago but my phone's battery goes down to 5% even when it was fully charged with the brightness on the lowest brightness setting. It is really aggravating when I have to charge it 2 -4 times a day. I get good grades ( all A's and 2 B's ) , do loads of chores and I'm responsible with my things. Everyone in my school has an Iphone and everytime I see their Iphones I feel really left out knowing that I don't have one. I have most of the money ( $ 40 short ) I'm willing to sell my flat screen tv to get the money for the monthly plan. I rarely get rewards for doing good things. My parents are the strict overprotective type who say no to a lot of things but I feel that since my family recently got rid of our home phone my 11year old brother should have my current phone for the times he is home alone. ( If there are any mean comments I will give you a thumbs down ) I have always been responsible w/ my things except for 1 time when I lost my phone 3 days ago and I still have not found it

How can I convince them thanks to all of the helpful answers.

Added (1). @ Joe I already get all A's

Is the gold iPhone 5s girly? - 2

They ran out of stock on the black and the sale ends before they get more. I don't know any guys that have it in gold and the silver is just too generic and lame

How to spy on my mans iPhone?

Recently I found out he was on a dating site and he claims he was just on there to delete it. But he won't give me his password to delete the account. We met on this site 5 years ago.
But anyways I was wondering if there was some sort of app or anything like that I can install on his phone in order for me to see what he's typing including passwords. Please don't comment on our relationship. I know dump his sorry but but I just wanna make sure. So can anyone help or tell me how I can do this. The account isn't tied to any of his email addresses so I'm assuming he made a whole new email I would like to see that aswell. So again is there any app that I can install or anyway I can see what he's typing like everything he does. I know you can on a computer because my family does that. But how can you do that on an iPhone?

IPhone 4 randomly turns off?

I have the iPhone 4. I have dropped it so the whole back is shattered. The front has some cracks as well and there's a huge chunk of glass missing from the front part near the camera. It still worked fine amazingly until about a month and a half ago. It turned off so I tried to turn it back on, but it wouldn't. Now If it turns off, I literally have to wait 1-2 days for the battery to go down and plug in the charger for awhile and if it comes on, pray it stays on. Last night it stayed on for about five hours, and just shut off. I JUST got it on again. It will probably turn off again tonight. My parents are trying to get me a new phone, but for the time being, this is all I have. How do I fix this problem permanently?

I spilt coca cola on my iPhone 4s?

At school, i spilt about half a bottle of coke in my bag and my phone was in it, it was quite wet and turned off, then when i tried to turn it on the apple logo came on and white writing at the top, now it won't turn on at all. I have it in rice but its not seeming to work (only been in there a couple of hours), will this work or has the coca cola damaged it? I have just got a new phone after losing my old one. Would apple or any shop repair it or will i have to get a new phone?

Free Unlock for Verizon iPhone 4s?

So I have a Verizon iPhone 4S. The Service has ended. My family bought androids on a cheaper family plan through another network. I didn't like the android so I'm stuck with nothing but my verizon iPhone that has no service.

Is there any way to unlock a Verizon Phone 4S for free without downloading anything onto my laptop? If I had to I'd pay a small fee but only if they accepted paypal for safety reasons.

What happens when my AT&T contract is up?

Well I have an iPhone 5 that I bought under a contract from AT&T. I was wondering how this upgrade thing works? Like do I have to pay for my upgrade? Do I have to repay the $150 I payed for not having that good of credit? Do I go back to AT&T or Apple? Basically how is the process into getting a new phone? And also what should happen if I wait and go past the 2 years to get a new phone?
