IO6 update iPhone 4 won't turn on

I woke up and my phone wouldn't turn on! I knew it was fully charged but when I plugged it in it came onto an IO6 page then said connect to iTunes. As soon as I disconnected it from charge it immediately turned off and when I plugged it into iTunes it keeps flashing to the apple logo then turning off and repeating. My computer is not picking up my phone because it will not turn on.

WHAT DO I DO!

Can't sign into App Store on iPhone 5?

I went to download a few apps for my iPhone 5. I entered in my account information to sign in, and it said the information was incorrect. I tried the option to reset by email, but I'm not getting any emails. It's saying the answers to my security questions are incorrect. I always keep my answers and information the same when it comes to login info and backup info, such as security questions. Could I have gotten hacked, and someone changed my info? How can I get around this and be able to sign into my own App Store on my own phone?

My iPhone 5 was sold to me with missing part

So here's my story for anyone that can give me helpful adivice…
I purchased my iphone 5 almost 3 months ago from this day… NEW from Verizon Wireless not refurbished or anything like that, I haven't had a problem with it up until yesterday it got really hot & turned off it wouldn't turn back on so I had to restore it sadly. So then came the next day which is today, I went to the nearest apple store from where I work set up an appointment with the genius guy because my iPhone shouldn't have done that to me. He told me I'm sorry for the bad news but your 1 year guarantee has been voided due to tampering with the phone so he told me that my iPhone 5 didn't have the 2 screws in the bottom by the speakers. Now I didn't notice my iPhone did not have those screws up until today, I'm so *** off I got no idea what to do… I need to file a claim because I'm 100% sure that my iPhone was sold to me like that it couldn't have fell off & I don't think Apple hand inspects every iPhone in the world maybe mine was unlucky so now to the point, I need help on what I should do like who to speak to & how to handle this. Please no stupid advice put yourself in my shoes. I paid for an item that should come with every part & I will fight this issue. I want my guarantee & an iPhone with all the parts it should have. I'd like to add that it's my first iPhone so no I didn't know screws went in there It looked like part of the speakers to me honestly.
