I got one, Put my name down for a 32Gb on launch when i picked up my mums 16GB , got email 4pm next day (25th June) to say they had it. Was a reservation that had not been picked up apparently.
I was on a priority list (got on it friday afternoon) and received my email this morning. I am not going because I stood in line at at&t this morning and got mine already. But i'd be heading to apple otherwise!
I got both an iPhone 4 on launch and an iPad this way. It's very convenient. I strolled in at 5pm and picked up the iPhone 4 on launch with no line. Rest assured you'll get one with a reservation.
