Iphones. What's the difference?

What's the difference between the iphone 4 and the iphone 4s? Or the 5 and 5s?

5S is not released yet (if that's what the new iPhone shall be called) :)

4S is an incremental/upgraded version of iPhone over iPhone 4
This has been Apple's naming patterns for iPhones eg:
iPhone, 3G, 3GS, 4, 4S, 5, …

4S has a lot more features than 4 (go to Apple.com for details) but the biggest difference is that 4S has SIRI, the voice assistant. It's pretty cool.

Iphone:
4 - 1ghz CPU, 3.5inch display 5 MP camera

4S - 1Ghz dual core CPU, 3.5 inch display, 8 MP camera

5 - 1.2 Ghz dual core CPU, 4 Inch display, 8 MP camera {improved }

There isn't Iphone 5s…

Iphone 4s has siri and iphone 4 doesn't. The iphone 5 is longer, thinner, and weighs less than both…

Most of the features are same in iphone 4 and 4s.
