Can I really exchange my iPhone 4 for an iPhone 5 at best buy?

Avia

If so, what is the string attached?

Also, will they accept my phone if the lock button is jammed?

They won't accept a jammed lock button, it has to be in very good condition if you sell it at Best Buy.

They will not accept this kind of phone.

Really confused about the cex exchange thing I'm selling a few games and 2 consoles and it says how much i will get and then it says "Exchange Total" and i really want to buy an iPhone and it says the price and "Exchange for" so if i sold all of the games for exchange stuff would I be able to buy an iPhone with the exchange total i get? I'm really confuse and i will be very grateful if you can help me out
Can you choose your phone number when you buy an iphone 5 at best buy? At best buy today you can trade in an old iphone 4 or 4s for a 150$ credit on a new iphone. Can you choose your own number if you buy an iphone at best buy, or is it just an automatic one? ** I don't already have a phone number btw **
Can you buy an iphone from best buy, and put verzion pre paid service on it? Verzion pre paid saids its 50$ a month. So if I buy a 99$ iphone from best buy. Can I put the pre paid service on it?
