Apple has seeded developers with iTunes 10.5.1 beta 3, sources tell MacDailyNews. The update includes a number of important stability and performance improvements for iTunes Match.
iTunes Match stores your music library in iCloud and allows users to enjoy their collections from anywhere, any time, on their iPhone, iPad, iPod touch, computer and/or Apple TV.
Once developers install iTunes 10.5.1 beta 3, they can turn on iTunes Match on each of your computers and iOS devices, sources say. On their computers, developers choose Store > Turn on iTunes Match. On their iOS device, they tap Settings > Music, then turn on iTunes Match. On their Apple TVs, Apple asks developers to turn off iTunes Match under Settings > General > iTunes Store.
