Someones been using their iPhone to surf the web

The latest gossip across the web is that someone has an iPhone and has been "testing" it's web browser out. MacRumors said they found the iPhone browser identification tags in their apache server logs.

Here's what the iPhone supposedly reports itself as:
Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A538a Safari/419.3

They also claim that the requests originated from Apple's internal IP addresses. Now most things like browser identification strings can be spoofed but we're not sure if internal IP addresses can.

Real? Fake? We'll only know come late June so we'll take it all with a grain of salt but wouldn't put it behind Apple to start testing the darn thing to see if it works. I mean they should right?
