Here are some of IOS changelog 5 beta 7 found so far:
- Bug fixes and general improvements in performance
- Automatic downloading of music with an American account
- Small update the iPod but causes a bug when updating via OTA, should remove the music and resync
Notice that this beta will expire on October 20, so it is very likely that iPhone OS 5 will be released around this time!
