Of the thousands of apps available for the iPad, a handful have resounded so well with customers that Apple is featuring them on a special iTunes page devoted to 40 of the most popular apps for iOS devices.
Since Apple opened its App Store service for iOS devices in 2008, mobile users have been downloading content at a rate of more than three billion apps per year. Now, the App Store's download counter is hurtling towards the 10 billion mark, and Apple plans to award a $10,000 iTunes gift card to the person who completes the 10-billionth download.
Ahead of the App Store's milestone, Apple has announced the most downloaded iPhone and iPad apps of all time. Categories include paid and free apps for both devices.
We recently posted the top free iPhone apps and noticed that Facebook's mobile app was the most popular on that list. However, Facebook does not appear anywhere on the iPad's list of top apps. That's because, as CNET notes, Facebook does not yet offer an official iPad app.
