Why does it say read on one & then on another it just says delivered?

On my iPhone when I'm iMessageing someone it just says delivered on it. But on my friends phone it says read at the time that i read it. And then on her phone she'll be iMessageing another person & it will also just say delivered? So I'm confused on how to get it to tell me when they read it or can i even make it like that?

Iphone is stuck at apple logo then shuts off by itself

I've had this Iphone 3g since chirstmas, and i've dropped it before, it's cracked, but not badly. And so it is updated though, to the new settings, like when i get a text it's green and i can just slide it to open it. And so two nights ago, i turned imessage on for the first time, then went to bed and the next day it wasn't working, and then i realized imessage was on, so i turned it off and it worked perfectly for about five minutes then i turned imessage back on to see if that was the problem, then it stopped working.

Then i turned imessage off and it still wasn't working. So anyway, now when i turn my phone on, it stays at the apple logo for a good 15-20 seconds, then it goes to the shutting off screen. And now it says low battery, i plug it in, then the apple logo comes on, then it shuts off again! I've dropped it before, but it doesn't make sense how it works perfectly one day then not the other. I've tried resetting it, holding the home and off button, and still not working.

Also it was going to the home screen when i turned it off, but then i turned if off and on so many times it just got stuck at the logo. Also, when it was working, i had no more space in my phone. Like for pictures, apps, music, ect. Could it be that? Oh and it's nothing with the internet. Help! I'm also thinking of bringing it to apple today. Good idea?

How to get rid of overage charges (at&t)?

I own an iphone 4, and my data plan is $20/300 gb. I went over my plan by 12.11 mb, so obviously I'm billed an extra $20 in my next bill.
What can I do to get rid of the overage charges? I really do not want to pay the extra $20. Should I switch to a new plan? Can I call in, and ask someone to get rid of it?
