AT&T (T.N) said on Friday it has seen extraordinary demand for Apple Inc's (AAPL.O) latest iPhone with over 200,000 pre-orders in the first 12 hours.

Pre-orders for the iPhone 4S, which was unveiled on Tuesday, started October 7. The latest smartphone from Apple left Wall Street and fans wishing for more than a souped-up version of last year's device, at a time of heightened competition from rival smartphone makers.
