I went to the Apple Store in Otay Ranch (San Diego) today and the Apple employee told me that she didn't have them in stock, and didn't have a clue as to when they would be getting them. She was guessing that they would be available on Friday, but was uncertain.
From the sounds of it, the stores are hit and miss. I guess I'll just keep trying back and hope to pick one up by this Friday when my 3G arrives. I don't want to order from the website and wait another 3 weeks. I've waited long enough for the iPad....this has been the longest month of April EVER.
