Microsoft will be hosting a number of developer camps for its WIndows Mobile platform in the coming weeks in at least six cities around the world. If you develop apps to sell or work on them for your enterprise, you might want to check these events out. The targeted platform is Windows Mobile 6.5.The camps are listed as "not for profit" so I assume there is no fee, though you'll have to pick up your own travel and lodging tab. The first event is August 19 in Redmond Washington on the MS campus. The other five cities are Austin Texas, London, New York, San Francisco and Singapore. Those dates haven't been established yet.

Targeted attendees are mobile developers, web developers, .Net developers, UI designers and testers. You can get more information on these events, including links to registration pages at the Windows Mobile Blog and the WinMoDevCamp pages.

Addendum to my AT&T Blocks Google Voice From iPhone post. I closed that blog post with a comment that users have a lot of animosity and resentment towards their carriers for blocking some cool apps and services, like Google Voice. I had no idea how much resentment there was. TechCrunch has a story about a prominent Mac OS X developer that is so frustrated with how developers and users are being treated by AT&T and Apple itself through the App Store that he is ditching his iPhone in favor of the Palm Pre. AT&T just lost at least $360 per year on data alone and probably closer to $1,000 per year for voice, texting and other services. Apple just lost a repeat customer. This is a person that is a huge Apple fan too. How many lost customers must they endure before the carriers learn?
