iPhone OS 3.0 update due at 1pm ET

If you've been tethered to your Mac since midnight, obsessively pressing the "Check for Update" button in iTunes, you can give it a rest. At least for a few hours. Engadget has deduced that today's iPhone 3.0 update won't get pushed out until around 1pm ET.

Its rationale?

Reports that carrier 3 in Hong Kong sent a network-wide SMS notifying iPhone owners that OS 3.0 will be available on June 18th, 01:00 local time. That's 1pm on the 17th in New York, 6pm in London, and 1900 in central Europe.

So there you have it. Another three hours to go.
