Sony did not update the Xperia V in Taiwan to the original 9.1.A.0.490 Jelly Bean firmware. Instead, the update went straight over to the new 9.1.A.0.492 firmware, which I have made into an FTF in the link below. Firmware includes some regional apps, all of which can be uninstalled.
EDIT: It is pretty obvious that the .492 firmware is not a large update in any sense, and could very well be a regional push-out update with minor bug fixes. On personal experience, I have not had any SOD issues (though I haven't had that on the old ICS firmwares either), but the weather widget still causes menu stutters and the Walkman app still has glitches in playback when switching tracks (long pauses).
