Weighing in at a hefty 817MB for the iPhone 4, build 9A5248d just hit the Developer site. There was some question as to whether Apple was going to deliver the update OTA but obviously that’s going to be later.

Update:

-WiFi sync now works with iTunes for Mac

-iCloud logo becomes silver in settings

-Lockscreen notifications got an update from the UI department
