Announcing its first quarter results during an earnings call with Wall Street analysts and reporters on Tuesday, Apple said that a boom in the iPhone sales, supported by the iPad, had helped the company touch record-high quarterly revenue figures.

Noting that the first-quarter sales of the iPhone were much higher than the earlier projections, Apple revealed that the 35.1 million iPhones which the company sold during the mentioned quarter marked a whopping 88 percent increase over the iPhone sales in the same quarter last year.

Moreover, the sales of around 11.8 million iPad units during the quarter translated into a two-fold increase year-on-year. Overall, Apple's sales witnessed a 59 percent increase over the last-year same quarter figures, with the $11.6 billion net profit also marking the company's all-time-high for the first quarter, and being two times more than its net profit figures a year back.

In addition, the $39.2 billion revenue which Apple reported for the first quarter also set a new record for any January-March quarter for the company thus far. However, the first-quarter revenue was nearly $7 billion less than the last quarter figures that set an all-time record for the company's quarterly revenue figures.

With the iPhone alone accounting for approximately 58 percent of Apple's first-quarter revenue - as against its last quarter contribution of 53 percent - and the iPad also witnessing a notable increase in sales, Technology Business Research's analyst Ezra Gottheil said the iPhone and iPad numbers showed "aggressive growth" during the quarter.
