Gingerbread 2.3.3 is now available via Kies! The entire update process took less than 10 minutes and absolutely no data was erased. All contact information and applications installed were restored automatically! Ran the Quadrant Standard benchmark a couple of times and got scores of 973 and 992. The performance seems a bit smoother than 2.2. Hopefully the phone won't hang anymore! I've also posted in the Indian thread but it's a bit tedious to navigate to the last page so thought I'd create a new thread itself.
