Just because the Olympics are over doesn't mean there's not a lot of things to do in London -- the iTunes Festival, for one. Today Apple updated its app for the festival. iTunes Festival London 2012 version 3.5 adds additional performance and reliability improvements, additional language support, and now the app is available in additional countries. The availability of the app in additional countries is important for those festival attendees visiting London but who don't have a UK App Store account.The 2012 iTunes Festival will run from September 1st to September 30th this year. Over sixty acts will be performing on different nights including Usher, Emeli Sandé, Jack White, Norah Jones, Plan B, and more. Tickets are free, but only available via online lottery. Once again the festival will be held at Camden's Roundhouse in London. iTunes Festival London 2012 is a free download.
