It's 1:30am here in the eastern part of the U.S. and Apple's online store is "being updated." The updating is undoubtedly to accomodate pre-orders for the new iPhone 4 -- which Steve Jobs promised would begin on June 15, 2010.
I thought that I'd stay up a little late and get my order in (32GB his and 16GB hers) after the clock struck midnight but it's been over an hour and I'm going to get some z's. Maybe he meant 12:00 midnight pacific time?
Regardless, the store should be back up soon and you'll be able to place your iPhone 4 pre-order any time now. Wait, you are pre-ordering an iPhone 4... right?
If you are, what model? If you aren't, why not?
Update: The U.S. Apple store is back online complete with iPhone 4 pre-ordering. Curiously, you can only pre-order the black model for delivery, the white model is for in-store pickup only.
