This might be a lame response, but why would anyone want to use a pre-paid provider for their iphone that cost them $400 bucks?! Wouldn't you be missing out on all the cool internet/data functionality of your iphone? I'm assuming your pre-paid providers wouldn't include data services in their offerings, but who knows..
The iPhone still has Wifi. I don't use PAYG, but i don't have a data plan. Whenever I need the internet, 90% of the time I am near a wifi point.
really? where do you live? In both DC and Boston I've had to use EDGE constantly while on the go. I've found I definitely cannot count on being able to find free wifi hotspots.
