I just recently received the Samsung I9100 Galaxy S II (running Android 2.3.3 Gingerbread).
I'm still playing with it, learning all the new apps & goodies.
It is a very, very nice phone!!
A huge screen (4.3inch) which looks great, it also runs like a scalded cat, thanks to the dual core 1.2GB processor.
