I'd be happy to sign up for 2-factor auth, but it doesn't work with Google Voice. The whole reason I use Google Voice is to keep my phone number independent of the device/carrier I happen to be using. It's my permanent address in telephony. Whatever number is on my SIM card is just temporary. If I used 2FA, I'd run the very real risk of locking myself out of my account the next time I change carriers. Knowing how Apple expects its users to commit to its product portfolio all-or-nothing, I don't expect an Android app, but it would be nice if Facebook and Apple would at least include Google Voice support in their SMS verification tools. (As for 2-factor authentication, they really should support the Authenticator project like everyone else.)
