It was just six days ago when we reported that Mango hit 20% of Windows Phones world-wide (17% in the US). The info came via the free app "...I'm a WP7!" which collected the data from its 83,000 users.

As of today, the number has hit 30% world-wide with Windows Phone owners in the U.S. following closely at 27%. The data sample this time is also much larger, with over 93,000 users now on board using "...I"m a WP7!", making it even more reliable and statistically significant.  At the current rate, Windows Phone Mango should hit a 50% adoption rate by October 22nd, less than 30 days after the update went "live" for a limited amount of users. Not bad, not bad at all for Microsoft's big-update.

One thing that is for certain, it will be interesting to see if Microsoft can deploy such a large update to scale once Windows Phone gains more market share. So long as the number of different Windows Phone devices stays relatively small (compared to Android), we think it shouldn't be a problem.

Pick up a "...I'm a WP7!" here in the Marketplace to see for yourself, as well as other interesting user stats.. (Thanks, Judge Daniel & TheWeeBear for the tip)
