I'm a mobile app developer. I was developing for Windows Mobile and Blackberry. I begin to dig into iPhone Development since Feb, 2009. Working has become a brand-new page for me and for my life.
I was working on a symbian app for a short time in March, 2010. And I begin to learn Android in Nov, 2010 and learn WindowsPhone in Nov, 2011.
Now I'm working on an iOS framework similar to iAd and I'm happy to offer all kinds of libs to help other developers.
Always walking down your own way and keep your faith.
