I'm a Software Engineer and have about 10+ years of experience writing realtime embedded software for printers using C++.
I took a "class" with other people from work to learn how to program apps for ios devices using Objective C. We finished up this class and were done May 16, 2012. This class took us about 3 months to do. This class is the 'audit' class offered on iTunesU at http://itunes.apple.com/us/itunes-u/ipad-iphone-application-development/id473757255. The demo's that he has mid-way through almost every lecture are very helpful.
Currently I am learning C# at work and writing applications that read/write data for a family of chips via antenna.
