Any compensation to old Iphone users?

So I got n Iphone for Christmas from my parents and I love it. But now just a short half a year later the 3G is right on our heels. When the first price cut came Apple refunded everyone who bought an Iphone previously. Will we get to see that again? The 3G sounds wesome, and I would get it for the GPS alone, but at the time with gas prices so high and me going to college in a few months I cant afford any out of control spending. I only have 1.5K to my name and this would be a sizable sum to be taken out.

Also, will AT&T be offering upgrades like normal phones when the 2 years are up?
