Android 2.3.4 has been leaked for the Samsung Galaxy S (that would be the i9000 international version), and the folks at SAMFirmware have made it publicly available. Early reports are saying that it does address some of the bugs found in the 2.3.3 version, but the all important video chat via Google Talk is not included in this build. We're not going to read too much into that, this is a leak and nothing official after all.
The real question is how long will this take to move from leaked status, to something that can be deployed across all carriers, for all Galaxy S variants. We don't have that answer -- I don't think anyone does. Hopefully it's sooner rather than later.
