Developers: Apple releases iOS 4 beta 4 for iPhone, iPod touch, iPad, Apple TV, iTunes 10.5 beta 4 for Mac

Apple has once again pulled a Friday trigger on an iOS beta, this time iOS beta 4 for iPod touch, iPad, iPhone, and Apple TV, as well as iTunes 10.5 beta 5 for Mac and Xcode 4.2 DP 4.

If you're a registered, paid developer head on over and grab it all now. If you spot anything new and noteworthy, let us know in comments, and discuss away in our iOS 5 forum.

UPDATE: We're getting a bunch of reports that iOS 4 beta 4 is showing up as an OTA update. We tried it and it errors out for us but let us know if you have any luck.
