San Francisco’s own Trevor Hewitt has launched a brand-new iPhone app dubbed Guest List Nation. This nationally operating application allows users to see what’s happening at favorite hotspots, from entertainment to cover fees, and even has access to the guest list. From the Bay, to Vegas, to LA and beyond, the app is customizable to the user’s geographical location to provide up-to-the-minute event information. Best of all, it even provides a validated visual guest list confirmation for those less-than-accommodating doormen. Waiting in line is so last millennium.
