I’ve just noticed that the “extra” Windows Phone 7 Jump Start sessions added at the end of October don’t seem to have been that well publicised (in a very unscientific check of the number of bit.ly links to them). So, in case you missed them, here are the direct links to the additional 7 sessions:
Session 13: Panorama and Pivots Session 14: XNA Deep Dive, Part 1 Session 15: XNA Deep Dive, Part 2 Session 16: Location and Bing Maps Session 17: Optimizing for Performance Session 18: Designing Apps Using Expression Blend & Metro Session 19: Ask the Experts podcast
If you didn’t know about the original Jump Start training, here’s a link.
