Looks like it was a very busy day for Apple and AT&T. Pre-orders for iPhone 4 brought the web to its knees. Twitter was atwitter (ugh, sorry!) with displeasure as users attempted to set one aside for themselves. As for exact numbers, I remembered reading today that it was over 1,000,000 pre-orders but I couldn’t find any sources that weren’t more than conjecture. That’s a pretty substantial number if it is to be accepted as truth. On top of this, only black iPhone 4′s are available. Expect white to also be a big seller when it hits the shelves. If Apple can sell that many, in one color, based only on a promise (like, you can’t even see the device in person) — then I think it’s safe to say, iPhone 4 is going to be HUGE. If you missed your chance, you’ll have to wait. Pre-orders are closed, sold out!
