Instead of just the iron you could try a relaxer, it won't take the curls completely out the first time but it'll make them a lot easier to manage. My friends ex has really curly hair like there is no way he could have straightend it without the relaxer, but with it he was able to straighten it no problem.
From what I can see in your picture, Your hair is awesome! :)
But if you want to change it, go get it permanently straightened. And it will stay that way for a long time. Then you could do pretty much anything you wanted to do with it. You can get it done at pretty much any hair place, well except for a barber shop.
You could try attacking it with straightening irons. But for curly hair that's just going to get troublesome.
Best thing to do is to suffer the humiliation of looking through a hair model magazine or a picture loaded girly mag. Or using a fashion catalog (like I steal pictures out of the next catalog) There'll be something in there for you.
