There were a lot of naysayers out there that said the Windows Phone 7 would be a flop. If the sales numbers in Europe and Australia are any indication, I’d say it was just the opposite.

According to a report in Digitimes based on reports from Taiwanese manufacturers, stocks of HTC’s HD7 are currently gone at German carrier O2, and Australia’s Telstra is out of the HTC Mozart. Last week, U.K. carrier Orange warned its retail managers about likely shortages of the Mozart and Samsung Omnia.
