Will the new iOS 7 for Apple phones be available on the iPhone 4S?

I'm considering getting the iPhone 4S… Does anyone know if the new iOS 7 by Apple will be compatible with it]? And also, when is it going to be released?

Yes it will be. It should be released when the new iPhone comes out. Which should be somewhere in September or October. Hope this helped!

It should be, but if its not compatible with 4s they will probably develop an OS update that will mimic iOS7

It doesn't come out until the fall, but you can get it right away if you register your device's UDID on a site like http://www.instantudid.com/.It's $5, and then you can install the beta before everyone else. I got it running on my 4S already.

Yes, and the 4, 5 & expected 5S.
September is when it is expected.
