Apple today seeded the fourth beta version of iOS 5 to developers, continuing progress on the next-generation mobile operating system for the iPad, iPhone, and iPod touch set for public release in the fall alongside iCloud. The new version is listed as Build 9A5274d.
We've yet to hear word of specific changes in the release, although it does appear that Apple has also issued it as an over-the-air update for those running iOS 5 Beta 3, although users are reporting errors when trying to access it via that method. We'll provide updates as more information surfaces.
Update: Over-the-air updating seems to be working now, and saves nearly 700MB of downloading vs. the full size download.
Update: BGR has the full change log.
Update: Several readers pointed out that to perform an over-the-air software upgrade, the iOS device must have at least 50% battery life left, or be plugged into the wall charger or a computer.

Makes me feel closer to iOS5
Edit: it doesn't appear to be working just yet.
NEW: If you are doing a OTA software update from beta 3 to beta 4, you will need to re-sync your photos with iTunes.
This is great news :)
