The monthly AdMob Mobile Metrics report has been released with data from February 2008.

A couple observations from the February data:

• iPhone traffic was flat in February. This may be due to the ‘novelty’ factor of people getting iPhones as holiday gifts around December/January, the spirit apparently didn’t grow in February.
• Blackberry and Nokia have been fighting out in the Smartphone world as top handset makers to access mobile ads via AdMob. Their rank on the network varies from country to country. Even SonyEriccson wins the battle in specific markets like the UK. This means that basically the Smartphone race is being won differently region by region.
