Should I get my iPhone 5 fixed or get a new 5s?

I have an upgrade with At&t Next and my iPhone 5 screen cracked. I can pay around $50 to get my 5 fixed by one of my friends and wait for the 6 next year. Or should I just use my upgrade for a new 5s?

If your contract is up, then I would trade it in and upgrade to a newer version as they take trade-ins even if damaged, so at least you get something back for it.
Its actually cheap to upgrade that way and you get a new one. Thats better then putting money into fixing an older (or broken) version, and 5S is a really good phone.
