The other side of the coin. While it's not a huge surprise that software development for Windows Mobile has dwindled, especially with the clean break of Windows Phone 7 around the corner, it is a bit shocking at how fast it fell. (See the other study today about number of apps users have by mobile OS).

According to iGR, last year Windows Mobile was "by far the most popular" in terms of number of developers writing apps for it. Flash forward one year later and it's now dead last.

The iPhone of course is number one with 53% of developers writing programs for it. Perhaps more telling is that more than half of those who currently aren't making iPhone apps, plan to do so within in the next year. Yowza.

Blackberry was number two, ahead of Android which was sort of interesting, though we imagine those two will swap positions very soon as Android has received lots of momentum in the last 4 months. No word about Windows Phone 7 and developer plans, though judging by the attendance at the Microsoft ReMix events, it's looking very good.

Unfortunately, we don't have access to the raw numbers which would tell us more.
