Apple over the weekend reopened its iTunes Match beta to registered iOS developers. Mac Rumors reports that the company sent out emails to developers, letting them know that the beta has been expanded to additional developers in the U.S. The email also notes that iTunes 10.5 beta 8 is required to use the service. iTunes Match is an upcoming $25/year cloud-based service from Apple that matches the songs in users’ iTunes libraries with songs available on the iTunes Store, uploading songs that can’t be matched, and subsequently offering the users access to their entire libraries across all their computers and iOS devices anywhere they have an Internet connection. The iTunes Match beta was launched late last month, but was closed for new signups shortly afterwards.
