The main ones that will be of importance to me are The Sencha Touch hands on workshop (Sunday 9 am), and the Mobile Development Shootout (Saturday 1:30pm).
As it looks now, I'd like to start of Saturday with the Phonegap hands on with Dean Peters:
this presentation will take you through some of the tips, tricks and traps in using technologies such as Twitter Boostrap, iScroll, Zepto.js and Eclipse to get the most out of your responsively designed HTML5 solution.Although, I am tempted to see the Angular session.
I mentioned above about going to Mobile Shootout, but after that I am torn on what to take. Probably, will go to the Design across multiple devices and platforms .
For the last session of the day, definately has to be Bootstrap with Steve Keator.
Like i mentioned above, Sunday starts off with the Sencha hands on.
Ending with Responsive Websites - Do I Need It? How Do I Built It? , and Mobile Security.
