My iphone 4 won't let me get past Connected to itunes?

I restored my iphone because I wanted to have enough space for the iOS7 update. It had resat everything on my iphone, and was in the process of restoring my apps and everything else when my computer overheated and shut down. Now every time I try to start my iphone, it won't let me get past the "connected to itunes". I hit "restore backup" again from my computer, and it just restarts my phone, and I go through the same steps of setting up Wi-Fi and then it just says "connect to itunes".

I hope this makes sense. SOMEONE please help me!

IOS 7 UPDATE: Can I still update my unlocked iPhone?

So I went to a friends phone retail store he unlocked my iPhone through a company wich gives u the code to unlock and then he connected it wit Net10 (AT&T). Pretty sure it was a legal unlock MY QUESTION IS: can I still update my iPhone 4S to IOS 7 even though my iPhone is unlocked? Because if I do I'm worried my carrier settings wuld erase and I wouldn't have a line with Net10 any more.

What would I need for good quality audio in a video?

I'm saving up my money to have a "studio" (not really) but I made a you tube video recently and used an app that recorded my voice while i was singing (i used my iphone mic) then I sent the audio to my computer then edited it to blend into the music. It sounded good to me! I don't have an ima so i don't know how to do garage band (do I need to buy a cd from bestbuy and download it to my computer) I also was planning to buy a mic. But what could i connect that too, or can I get a usb cord that transfer the music to my computer? Basically I want to get as less equitment as i can, so I'm thinking I would need a mic, a mic stand, a pop block thing (can't remember what its called at the moment) anything else? If this is all i need, just tell me so, i want to be sure when i buy what i need!
