iPhone turns 5: What's next for Apple device?

(CBS News) Millions can't imagine life without an iPhone. But it was just five years ago that the first ones went on sale. Since then, consumers have learned to love touch screens, and particularly, apps.

Apple iPhone revenue hits $150 billion in five years, says analyst

But what can consumers expect from the rumored "iPhone 5," expected to debut this fall?

Referring to photos apparently leaked from a Chinese Apple factory, David Pogue, New York Times technology columnist, said on "CBS This Morning," "(The next iPhone is) the same size and shape, but longer, like a wider screen."

He added, "We know that Apple could not get away without making it 4G, which means just faster on the internet in big cities. And to make it 4G, it has to have a bigger battery, because 4G slurps down power like crazy. I think that explains the larger size."

However, the famously secretive Apple seems to have put a lid on its latest rumored device. Pogue said, "Other than that, we don't really know much."
