Facebook's mobile usage continues to grow at an alarming rate and according to a new study by comScore, more people are accessing Facebook through smartphones such as iPhones and Androids than personal computers. The 'Mobile Metrix' report was released on Monday and the numbers reflect data collected for March. It appears that Facebook users are accessing their walls and messages on their smartphones to the tune of 441 minutes or 7 hours and 21 minutes in the month of March alone. People who checked Facebook on their PCs accounted for 391 minutes or 6 hours and 31 minutes.

The report also says smartphone users access Facebook more than any other social media network including Twitter, LinkedIn, Pinterest and Foursquare. Because of these numbers, Facebook is now the second largest mobile property, second only to Google.

The numbers also reinforced something that Facebook was already painfully aware of, the fact that they generate very little revenue from their mobile app and a better mobile strategy is key in FB's continued business success. Their app does not include ads and only recently began including "sponsored posts" in users news feeds.

Facebook understands that they have struggled over the last couple of years to develop a unique app for their services. They also understand that failure to implement the right strategies for mobile users could be very costly in the near future. Could Facebook develop its own cellular device? No official announcement has been made about such a device, but it is believed that such a device is being secretly worked on.
