The rollout is such that when you successfully claim money you've been sent, you'll be able to send money from Gmail about 30 minutes after that. (It will be a couple weeks if your account is on an Apps domain and your domain administrator has not opted in to the faster feature release cycle.)
We're sending money to the I/O attendees first, and then they'll be able to send money to their friends, and so on.
