My Case Study Question :)

Question: How has the iPhone changed the phone market?

I have chosen this question, because the smart phone is really up to date, and everyone i know has one. I really love smart phones, and you can do so much with them, and they are always talked about in the media, so  think it will be a interesting topic to do.
The texts i might be interested in is the new iphone 4S and also the three day crash of blackberry messenger.
I also want to talk about the first smart phone, and also how many different smart phones we can get on the market today, and how they are different from a normal phone.

Here is some links to websites i may use:

How people have changed because of smart phones
