I have an iPhone 3GS and I only have the apps that came with the phone. I don't know, but when I learned that I had to give a credit card number even if all I wanted were free apps I said that I'll get by with the internet access. I hate to put card numbers out there where all kinds of bad things can happen, I use cash whenever possible. Anything that I've ever wanted to find is on the web somewhere, and then I add an icon to the homescreen and it's basically the samething as an app. I got by with the standard cheap upgrade phones for years and while they did the job, smartphones are just plain cool. When I went to look at new phones a year ago I looked at this one and that one, and then saw the iPhone display over in the corner. I knew that once I started playing with it that I would have to get one.
