Pwn2Own organizer expects Safari to crack first, and turns its attention to mobile phones
This year they'll be looking at all major browsers on both Windows 7 and Vista, and Mac OS X Snow Leopard. $60,000 of the $100,000 total prize fund is allocated to mobile phones, however -- the rules aren't clear yet, but the four phones being scrutinized are the Apple iPhone 3GS, RIM BlackBerry Bold 9700, a Nokia device running Symbian S60 and a Motorolla device running Android.
I can't find any speculation on which of the mobile handsets are likely to crumble first -- Portnoy definitely thinks that Windows 7 is more secure than Snow Leopard though! "...Snow Leopard isn't on the same level as Windows 7."
