Kind of seems like this must have been a somewhat urgent fix for something that we probably won't ever know about. This is by far the fastest I have ever seen sprint roll out an update. Everyone I know - including myself - got the update OTA with in 24-48 hours of it being announced. And it showed up almost immediately in KIES as well as sammobile.com. The last update - OD3 - took almost a month to show up on sammobile.com or OTA for a lot of people. And it was obviously fairly substantial at just over 300 MB. I just wish every update was pushed this quickly.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
