I received the following email:
In addition to the rich set of resources currently available to you in the iPhone Dev Center, we’ve just added new resources to power your development as you create world-class mobile applications with the iPhone SDK.
Thank you again for applying to the iPhone Developer Program. We’re thrilled with the tremendous response we’ve received. We have many more requests than we can serve during this initial beta period, so we must limit the Program at this time. We plan to expand it during the beta period, and we will contact you regarding your enrollment status at the appropriate time. We appreciate your patience.
I’m not in yet, but at least I’m not out either.
