Should I keep my broken iPhone 4 or buy a 5c?

I've had an iPhone 4 for 2 years (it was my mom's before that), and at this point in its existence the screen is cracked and there's no home button. I could fix this for $100, but that's how much the 5c costs.So, for all you up to date with technology people, should I sell my broken 4 for about $20 and then by a 5c for $100 (which would be around $80), or just fix my 4? Or something else?

I'm not bothered with a long explanation so i'm just gonna say yes you should sell it now befor it become less valuable (get it fixed first)

If you are up for an upgrade, I would just go for the 5C. If fixing your 4 costs the same as a new phone, why not just get a new one? I think buying the 5C is a better option, because if your repair doesn't go smoothly, you could spend more than you wanted to fix the 4.

No way I would pay to fix an old version if your contract is up, put that money towards the new phone instead. You can get a new contract and trade in the 4 at the Apple store to get some money off, I would go that route.
