My iPhone says software up to date when ios7 came out

At around 1:52pm my iPhone said that ios 7 was available but now my setting say that my software is up to date I don't understand what's wrong! :/

It needs to be an iphone 4 or newer in order to update.

They are trying to limit the number of updates so the servers won't be overloaded. They are trying to release in segments depending on where you live. I had the ability to update my iPhone 5 at around 2 today and now I'm unable.
