A resourceful poster over at XDA has gotten his hands on a pre-release version of the Jelly Bean update destined to eventually make its way onto the Verizon Galaxy SIII (S3). The device received an incremental 4.0.4 OTA just a couple of weeks ago, and its brother on Sprint has started officially receiving the 4.1 OTA, so the timeframe on this makes sense. The poster is quick to point out that this build is not finalized, with a build date of October 8th, and that he believes the official OTA will hit in the coming weeks.
Take that with a couple boulders of salt, but at least for now those of you on Verizon with the Galaxy S3 can get a little taste of the pre-release build if you're so inclined. A couple of custom ROMs based on the leaked images have already hit the forums, but as always, flash at your own risk.
