Our tip lines, and all of Twitter it seems, is afire in claims that some iPhone 4 are already on delivery trucks and even in users' hands. Hey, crazy things happen in crazy times but we'll believe it when we see it (in non-blurry cam pics, in your real-life full-framed hands, okay?)
Given those Apple emails about iPhone 4 pre-orders arriving a day early, FedEx confusion could see them moving around already. Or some people with nothing better to do could be using that uncertainty to play internet pranks just for the lulz.
UPDATE: Looks like, indeed, some deliveries have gone out early. Picture above is courtesy of a Twitter DM. Check out the TiPb iPhone Forum for more pics, and if you get one early, post your own ASAP and tell us what you think!
