As far as I'm aware T-mobile, three and possibly orange too, have not yet released their 2.2 updates.
I could be wrong though
Confirming this, sorry guys
. There are also 2 versions of the galaxy S if you're on Orange. I'll be blunt and say one is just stock Galaxy S android 2.1 + 2 orange apps (films, account, removable) , the other is a re-branded heap of crap in which we did some really stupid stuff like remove gtalk again. We changed over around october. I did the kies reghack fix to get JPO on mine anyway.
