iOS 4.1 is now live, bringing:

  • Proximity Sensor fix for iPhone 4
  • Game Center
  • iTunes TV Show Rentals
  • Support for Apple’s new social network, Ping, built into the iTunes app
  • HDR Photo taking, which automagically cleans up pictures by combining multiple, simultaneously-taken shots into one
  • HD Video Uploads to MobileMe/Youtube over WiFi

iTunes in the UK doesn’t seem to have the update yet, but keep checking!
