Good news for those of you who managed to order a Nexus 4 last week but were stuck in limbo on shipping -- it looks like another batch has started shipping. Actual delivery date is still kinda up in the air, but that's not unusual for UPS; it can take a few hours for the tracking system to catch up. Check back in the morning.
Either way, this is a step in the right direction. Guess we can lay off the form letters now, eh?
