Is there going to be Ios 7 for iPhone 4?

Mn I wonder if ios 7 is gonna be compatible with iPhone 4?

Yes. Support was dropped for the iPhone 3GS and the iPod Touch (4th generation) only. Supported devices include the iPhone 4 and later.

Yes but not all features will be available on the iPhone 4 - as detailed at the bottom of…

Yes, it will be compatible, but it doesn't come out to the public until the fall. If you want to install it early, you can register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you can try out the new OS before everyone else. That's how I got it on my 4S.
