AT&T Samsung Captivate I897 Firmware I897UCKH3 Android 2.3.4 Gingerbread is online!

New firmware for Samsung Captivate I897 AT&T leaked. I might say that some devs have managed to pulled directly this from Samsung's FUS (Firmware Update Server). I also read today on a twitter feed I subscribed. It was marked as I897UCKH4 but after I downloaded it, in the archive it was I987UCKH3. This is a leaked version usually the announcements are followed by a Kies official release within a few days. This is an upgrade version of Android 2.3.4 Gingerbread firmware with a build date of August 8, 2011, since  from previously released Android 2.3.3 I897UCKF1 last July.

Anyway,  the I897UCKH3 Android 2.3.4 Gingerbread stock ROM  is now available via Samfirmware.com link only for those advance users of Samsung Captivate who wants to try it out.

Samsung Captivate users who are not familiar flashing stock ROM, can wait the Official release later..
The only issue just for now is that there is no rooting method yet works in this version.
