Sleeping. Even if you're a developer who works until 4 or 5 AM even and sometimes especially on a weeknight, it's your duty to sleep through that time on that day because guess what? That's when Verizon releases the iPhone 4 to existing customers. Take a rest, take a nap, even watch a movie. It's your time to relax and smell the roses, because that phone costs $90 a month that'll be put to much better use for you -- soda pop and USB cords.
