Tomi Ahonen (blogger, author, speaker etc) has been crunching numbers and has come up with the world's largest companies in mobile, having stripped away other revenues. No small task.

Before we cite his Top 25, mobiThinking would like to thank Tomi including mobiThinking's Valentine's round-up in this week's Carnival of the Mobilists (if you don't know it, the Carnival selects the best mobile blogs of the previous week, so it's an honor).
