Why can't i download Apple IOS 6 yet?

Apparently apple iphone software IOS 6 is supposed to be released for download/update today (19 Sep) in Australia.

Does anyone know why my iphone still says i have the latest software update?

Added (1). Gjkd - did not answer my question at all…

Apple releases their software updates sometime between 9 am and 12 pm pacific standard time - which is currently GMT-7. Considering it's about 12:30 am in Cupertino, CA, you'll be waiting at least another 8 and a half hours.

Apple usually launch iOS updates in the morning US time.

This means that the update should be available from about 2:00pm on the 19th September.

Its not out yet. Its 6:13am in Cupertino where Apple is based. 10:00am is when they are expected to release it.

10:00am PT (Pacific Time) to be more accurate.
