As the concept of the mobile web gets a little more popular, it’s interesting to see what kind of websites people are viewing on the tiny screens of their smartphones. A recent study was conducted by M:Metrics to address this very issue, determining where smartphone users spend the majority of their time online.

The survey concluded that smartphone users spend an average of 4 hours and 38 minutes browsing the web on their phones. Of that time, an average of 1 hour and 39 minutes is spent bandying around on Craigslist. The second most popular online destination for smartphone users is eBay with an average of 1 hour and 29 minutes each month. Add these two sites together and you have over three hours of searching for other people’s old junk!

Coming in at third and fourth place were a couple of social networking sites. MySpace clocked in at 1:25 and Facebook logged 1:24. I guess after buying all that junk, they were anxious to share their new purchases with their online friends.
