London. 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 would work from yesterday. Bloggers, Facebook and Twitter users complained they missed flights or were late to arrive at work, as the alarm built into Apple’s iPhone failed to go off for a third straight day for some users. The problem was not limited only to the iPhone, with some owners of other Apple products, such as its iPod music players, also complaining of a similar problem with their alarms. "Apple certainly needs to fix it as soon as possible, but I doubt this will impact sales or reflect negatively on Apple itself,” said Gartner analyst Carolina Milanesi
