SprintGurus has the date of the Pre launch (as opposed to pre-launch) on June 7th, the day before WWDC. We’re not seeing any hard evidence in the image they propose but it makes sense for Palm to be out of the gate first. Will this take the shine off of iPhone 3 or will this just be the "Pre-event"? We are still hedging our bets on May 17th.
In related news, WWDC sold out in record time this year.
