iPhone is 'unavailable' in UK and US Apple stores; 3G release imminent?

As many of our intrepid readers have pointed out, iPhones are unavailable at the online Apple Store in both the US and the UK. As we mentioned earlier in the week, cell carrier and Apple retail stores on both continents are reportedly facing shortages as well.

With all the buzz surrounding the 3G model, the international rollout and the SDK, this is just one more sign that the release of a new device is right around the corner.

While I'm obviously not privy to any official dates (or even unofficial speculation), my past experiences in the cell phone retail world lead me to believe that an early June release seems very, very probable.

Thanks to everyone who sent this in!
