The iPhone and Mac sales scaled unprecedented heights during the quarter ended March, allowing Apple to pocket more than expected net profits.

Apple's net profits jumped 95 per cent to $5.99 billion during the three months between January and March, considerably up from net profit of $3.07 billion in the corresponding period of last year.

Total sales jumped 83 per cent from $13.49 billion in the year ago quarter to $24.66 billion this year.

Apple sold 18.6 million units of the iPhone between January and March 2011, which represents a growth of more than double from the 8.75 million units in the year ago period. Mac sales, at 3.76 million units, represented a growth of 28 per cent from last year quarter.

However, the iPad tablet sales stumbled to merely 4.7 million units following a massive Christmas rush in the preceding quarter.

The iPod sales, which peaked in the Christmas period of 2008, kept on falling both in annual as well as quarterly comparisons, to 9 million units, representing a fall of 17 per cent year-on-year.

Apple's Chief Operating Officer Tim Cook, who is in charge of Apple as CEO Steve Jobs is on medical leave, said that the disastrous earthquake and tsunami in Japan would hack revenues by $200 million in the running quarter. However, he stressed that there was no disruption to Apple's supply chain.
