Hi there,
Most of the basic user information (including photo) is available without permission.
The reason this is a priority, at least from my perspective, is that most fb users are not savy enough to understand the allow screen. They get nervous and wont add it. Even my friends have told me they wont add my app because they got scared away by the allow screen.

Ciao 4 now,
