How to get an iPhone 4S replacement?

I have an iPhone 4S. It is currently still under warranty. So my iPhone has multiple issues wrong with it. The first one is that the battery life is HORRIBLE. I have went to Apple over this before, but they told me to do a software restore. My phone also has issues when it rings. Sometimes it will ring.other times it will not. Sometimes the screen will go black for a little while and then come back on. This isn't an all the time thing. It does it often and it gets very annoying. Also. The screen will flash when somebody calls me sometimes. These ring issues happen regardless of whether or not it is on vibrate or loud. Also, my phone gets VERY hot sometimes. This can be while watching something on HBO Go or just charging. I mean it gets VERY hot. It's been to where it has made me uncomfortable to hold. I'm just wanting a replacement because I know the warranty will go out sooner or later and I don't want it to become an issue later. What should I do and do you think these are valid reasons for the Genius Bar to give me a replacement?

I paid 350 and the sound quality is amazing on my iphone 4s. People say they are a waste of money, but the people who say that is because they can't afford them.

My New IPhone isn't sending messages?

I just got a new iPhone 4s today, and some of the text messages arent being delivered properly. I have good service and there's no initial sending error, the people I'm texting just aren't receiving the messages. It has so far worked with two numbers out of around ten. Those two numbers are both long distance. No one local is getting my texts. Any advice because I paid a lot for this phone and plan, and it's starting to piss me off.
