You worry too much! They said you will have it the 30th and your already seconding guessing their online services? Check the calendar, it's only the 29th. You will have it on time. Don't worry.
Same here (for my wife's 16GB 3G - no tracking info yet for my iPad 3G). However, I thought priority shipping meant we would receive them by 10:30am. Nonetheless, I'm glad we will have them tomorrow - finally.
Mine says it's shipping from Jonestown, PA, and the status is currently "Shipment information sent to FedEx", and the estimated delivery says "Estimated delivery
Apr 29, 2010 by 3:00 PM." Hmm... But it also says, "Anticipated ship date
Apr 28, 2010", and info wasn't received until early on the 29th. We'll see.
Mine said that at first this morning, coming from Middleton, PA, it said ship date was April 29th and Estimated delivery was April 29, but I checked it 1 hour later and the delivery date changed to April 30th by 3pm.
