On cue, Apple has just seeded iOS 5 beta 4 to developers. The biggest change? It’s an OTA update… finally! The build itself is 915274d and it comes exactly two weeks after beta 3 was pushed out to devs. There will most likely be another one or two beta releases until the GM (Gold Master) as well â€” iOS 5 will be released for the iPhone 3GS, iPhone 4, iPad, and iPad 2 around September.
UPDATE: Apple’s full change log for iOS 5 beta 4 can be found here.
