iPhone 4 VS iPhone 4S

It is finally happen. The latest generation of Iphone is out, but it is not the iPhone 5 as many of us speculated. All the hype about the most up to date generation of the Iphone comes to an end with slight disappointment from the consumers as well as from the Wall Street. Well, we can see that the shares drop to 350ish level when it announced the iPhone 4S.


So, what is the most closely kept secret about the iPhone 5? There isn't one - yet. The new iPhone might be a little bit faster, has a better camera and allows you to sync content without needing a computer. It includes a futuristic, voice-activated service that responds to spoken commands and questions such as "Do I need an umbrella today?". But the real question is, do the current iPhone users need to upgrade to the iPhone 4S?

Anyway, back to the topic. I am comparing the iPhone 4 and iPhone 4S at the moment, and will be comparing the iPhone 4S with the current "king" of smartphone, Samsung Galaxy S2 in the near future.
