ThinkComputers posted a review on the What To Expect From The Next iPhone

A quote from the article:

Below is a direct quote from Think Computers on where they think the iPhone is headed.

"If Apple follows their typical release schedule, the new iPhone will be available sometime this summer, and the rumors are already flying about what that’s going to contain. With rival phones from Android stepping up their game, will Apple feel the pressure to do something completely new and spectacular? Maybe it’ll be like the 4S, which made small improvements to the iPhone 4 but didn't break out of the mold too much. Nobody really knows, as Apple hasn't provided us with any official information yet, but there are some of the speculated changes."
