In 2010, WWDC 2010 was announced April 28, 2010. WWDC 2010 was held at Moscone West, San Francisco from June 7 to 11, 2010. Apple reported that the conference was sold out within 8 days of tickets being made available, even though tickets were only available at the full price of US$1599 (2009 and prior, tickets could be bought with an early-bird discount of US$300). On June 7, 2010, Apple CEO Steve Jobs announced the iPhone 4 and the renaming of iPhone OS to iOS. The FaceTime and iMovie app for iPhone applications were also announced. For the bash held June 10, the band OK Go played at the Yerba Buena Gardens. Attendees received a black track jacket with the letters "WWDC" across the vest and the number "10" stitched on the back.
