Apple has just pushed out iOS 5 beta 7, another over the air (OTA) update for iPhone, iPad, and iPod touch. Go
It apparently hasn't shown up in Apple's development portal yet, but I imagine it will shortly along with the Apple TV beta 7, iTunes 10.5 beta 7, Xcode, and perhaps new iCloud betas.
UPDATE: It's available for download from Apple's developer center now. [developer.apple.comhttp://www.developer.apple.com)
No word yet on new features, if any.
