I accidentally turned on my data roaming?

But it was only for like an hour. Will I be charged a lot? I'm new to this iPhone thing.

No you won't. If you're using Sprint then you're a ok. They do not charge for roaming.

If you are in your home country then it won't be a problem as it shouldn't do anything. If you are in another country and they have roaming enabled, you could be charged!
