I want to download iOS 7 for my iPhone but I don't know where to download?

I'm trying to download the iOS 7 for my iPhone 4S I don't want a developer or a UDID thing. I can't find anything. Can anyone please help me find a link to download iOS 7 for my phone. Or Can you give me a link.

Thank You.

Follow these steps on iPhone:

Goto your Settings app ---> General ---> Software Updates

The phone will check for updates if connected to the internet. If no updates appear, iOS7 is not supported for the model you are using.iOS7.

iPhone 3G will not have iOS7 support.
It is unknown to me wether or not it is available for iPhone 4 and 4s (haven't checked yet). Chances are possibly.

IOS 7 won't be released until this fall
