Is ios 7 available for iPhone 4G?

Just wondering if its available for my previous phone Iphone 4G. Not 4S, but 4G.

Yes it is!

Yes. You can download it to your iPhone, but do some more research because I heard you have to do a save copy of your info and then put it back with the new iOS

Yes!

1. Its not called the iPhone 4G. Just 4.
2. Yes it is.

There's no such thing as the iPhone 4G. You have the 4 and the 4S. 4G is a cellular data type.

Yes it will be. It will be available to iPhones 4 and higher will be compatible with iOS 7
