I'm going to Apple's WWDC this year and I'm pretty excited to fully dive into iPhone development for the whole next week. That it takes place in San Francisco is a nice bonus, as well.
The conference is mostly covering iPhone related topics. There are rumors that Steven Jobs will present the new iPhone on Monday's keynote. I'll make sure I won't miss that. My schedule for the week is already planned with topics like game development, multitasking and user interface design.
If you are going to WWDC as well and would like to meet up, let me know.
