I have upgraded my iPhone 4 (Singapore) to IOS 5 along with my iMac and Win 7. All are working fine except that I cannot find ‘Find My Friends’ and iMessage feature. Don’t know where to look for it. Will wait for other users….
Find My Friends is a separate app that you have download, iMessage is built-in right into Message app, unless your friends have iMessage enabled, when you send him a text, it will be come blue instead of green.
