(Reuters) – Some
iPhone users in Asia and Europe complained of malfunctioning alarms on
the first working day of 2011, even after Apple reassured users that its
phones’ built-in clocks will work from Monday.

iPhones in July-September quarter, more than ever before, and is now the
world’s second largest smartphone manufacturer behind Nokia.
