In response to your comment about Safari always going to the desktop version, it does that on my Samsung i730 too using Picsel Browser. I wanted the Gmail App so I went to gmail.com/app and it took me to the desktop version in which it said to go to gmail.com/app on my mobile browser! Frustrating!
In the activation section you have a picture with a GoPhone SIM, can you use prepaid on the iPhone? How would data work?
