A post on Samsung Mobile Romania's Facebook page seems to suggest that Romanian Galaxy S phones (and presumably other European models) may see an official update to Android 2.3 Gingerbread by the end of March.
Translated into English and cleaned up a little, the post reads:
"The update to version 2.2.1 for Galaxy S will be available until 20 March, and Gingerbread (2.3) until the end of the month."
Our Romanian is a little rusty, but we think it's safe to assume the last part of that statement means either "it'll arrive by the end of the month", or "it won't arrive until the end of the month". Either way, it looks like the European Galaxy S could soon claim bragging rights as the first non-Nexus phone to get an official Gingerbread update. HTC has announced that Gingerbread will be coming to some of its older phones, but these updates aren't due until sometime in the second quarter.
