iPhone 5 pre-orders will begin tonight at 12:01 am Pacific Time (that's 3:01 am ET, 8:01 am BST). Sprint will star pre-orders at the same time, Verizon will start 1 minute earlier, and AT&T... hasn't said yet. Apple, for their part, has confirmed the time to Wired.
If you are going to brave the web tonight, make sure you join our waiting for iPhone 5 pajama party. We'll be hanging out with the staff and readers, having fun, and giving away cool accessory prizes to the people posting.
