I want the iphone 5c, but I can't get it?

The iphone 5c recently came out and I really want to get it for my birthday which is in one month. However, I'm in a two-year contract with AT&T and I have to stay with my iphone 4 for one more year. I'm so thankful for my iphone 4 and I really don't want to sound ungrateful, but the iphone 5c is just very cheap and it would be the perfect birthday present since I can't think of anything else to get. If I try to buy the iphone 5c before the two-year contract has been completed, it will cost around $500 to get the iphone 5c. That's just way too expensive and I don't know what to do about it. I was thinking about getting an ipod touch 5, but that would also be expensive, costing $300. What do you think I should do about this? All answers appreciated and thanks for reading.

You're locked in on contract, so there's no way to upgrade without paying an early termination fee and then renewing your contract again on AT&T Next where you don't have to really worry about early termination fees since you can upgrade your device every year on Next.
