Yes, thats true. And you can make Video now too. With the OS Update 3.0 for the 3G you can't do that. But there are already programs (jailbreaked of course) you can take videos. So its technichally build in the 3G.
I'm a bit angry about Apple. I bought from some months the iPhone 3G 16GB white and thought there won't be any new iPhones soon. I was wrong. Now there is even a 32GB Edition. Apple... curse you!
