iPhone 5 Day is coming, and you know what that means. That's right--long lines are already starting to form outside Apple stores all over the world as folks clamber to get their hands on the all new slimmer, lighter and faster iPhone 5. A shout-out to Gary's Guide member (and founder of a new social media startup, Vibe) Hazem Sayed, who is first in line outside the iconic 5th Avenue "Big Glass Cube" Apple Store. Go Hazem!

My friend Dave Lifson (product manager at General Assembly) along with Christina Chaey (associate editor at Fast Company) will be doing a free livestream this Wednesday at 2pm EST, on product management for non-product managers.

And did I mention its free? :) Oh, and everyone who registers gets a free copy of Reddit co-founder Alexis Ohanian's new e-book, Making Something People Love. So go sign up!
