What new features does the iPhone 5 have?

When does this phone come out?

What features does the 4 have?

Look it up online, but everything is rumors right now. The rumored date that they will introduce it is September 12 though. Things I've read are that it will have a bigger screen, newer more powerful operating system, made of stronger materials, plus much more if you look it up on the internet. Hard to say what's true and what isn't however at this point.

While almost everything is just speculation, the iPhone 5 will likely have a larger display, 4G LTE connectivity, a slightly different design, a faster processor, and iOS 6 out of the box. There's no official confirmation of a release date as of now, but most rumors point to a time in September-October. The iPhone 4 is similar to the 4S but lacks Siri, the faster processor, and the improved camera.
