I don't believe that retail stores accept Xbox's any longer and you're likely to only get about $20 for it... so... I would keep your old one... save up some money and get the new one... maybe put it in your birthday / Christmas list too... if you don't get it within the first year or 2 that you requested it, ask your parents.
You can trade the Xbox 360 for store credit, and with that you can put it towards the new Xbox 360.
I would trade a ps3 for a xbox 360
Maybe for an Xbox not a Xbox 360
No. You can trade in your xbox for whatever they will take and save money to combine until you get a 360, but you can not turn a regular xbox into a 360.
No.
Probably not, but you can trade it in for money, and use some of that to buy an Xbox 360. The main reason for this is that the PS2 is not as high=profile and new as the Xbox 360, which is considered a much better console. If you want to trade something in for an Xbox 360, it should be as high-profile and desirable as an Xbox 360 itself.
Yes. It doesnt mean that you will get the Xbox 360 for free though. i know that but how and where
Sure if you add the the money for a Xbox 360 minus $20
not a 360
No
if you trade and pay the difference at a pawn/trade store like entertainmart or gamestop
No only trade towards a PS3 you still need to purchase the PS3 after being given a trade in credit based on there lower trade in value for your model Xbox 360
