ID345 is hosting iPhoneDevCamp from August 1-3 in Denver. This is a satellite event that will include the ability to watch the keynotes and participate in the nationwide Hack-a-thon. The event should offer something for every skill level and be very "un-conference" like. If you're interested in all things iPhone and iPhone development, you'll want to be there. More info about iPhoneDevCamp is here.
