Apple has just sent out an email this afternoon notifying developers that iTunes Match has re-opened for developers, after registration was shut-down shortly after it launched. Sadly, we’re hearing from several people around the web that they still aren’t able to get in, but some lucky few are. Frustrating, huh?

iTunes Match allows users to store their music library in iCloud, where it can then be downloaded to their iOS devices or other Macs. The service is currently available to developers for $24.99 a year, but it will see a public launch alongside iOS 5. Let us know in the comments section below if you’re able to get in.
