Yea I will be going to CanSecWest for the first time this year. I'll have a talk on my favorite subject: Mobile Phone Security (Random tales from a mobile phone hacker). I'm really looking forward to this!
Second, there will be a mobile phone PWN2OWN again this year. They increased the cash pool for mobile devices to $60K, this looks like a statement! The devices/platforms are: iPhone (of course), BlackBerry, S60 (Nokia), Android.
