I May/Or May Not Get An iPhone Tomorrow! Please Give me Info?

I have been wanting an iPhone for a long time, and I finally convinced my mom to say yes. My dad has not been so sure though. I wrote an essay to prove that I'm responsible enough to get one, and he said Let me see how well you guys act. That was about 3 days ago.

So Tomorrow We're going to the city to go to the Movie Theaters and Have a good time, and my dad is in South Carolina, so he will not be in the car with us.
My mom will stop at Verizon to get me the iPhone 6s if my dad approves.
But, I will probably have to call my dad and tell him, "Hello Dad, We're waiting outside verizon right now wondering if I could get my iPhone now." Then I would talk about more responsibility.
Does Anyone know how I can SURELY get my dad to say Yes?

IPhone Battery Heating Up Fast?

Hi, I recently broke my iPhone 4s, and decided to take it apart, when I did the Li-ion battery was bent and started to heat up. Is it going to catch on fir, or blow up?

Is there any possible way to get my iphone fixed?

My old phone broke, and i got a new one and it fell down a flight of stairs and completely cracked on the side, -.-"
anywho it got a bit of water in it and its battery was 2percent but i was too lazy to charge it, so it froze and shut off and its been 2 days and it won't turn back on -.-"

So i thought it may be water damage so i gave it to a phone store to fix it, and the guy said its NOT FIXABLE! Any who i can't get another new phone so do you think if i change the battery it'll work?

I tried hard reset and everythng else.
