We just received an invite to a "Mobile Event at Facebook HQ" scheduled for Wednesday Nov 3. No press release, no fanfare, no inkling of what it might be, just the invitation. When thinking to ourselves, "Why would Facebook invite Android Central to their big Mobile shin-dig?" we can come up with a few answers. Maybe there's going to be a new and improved Facebook client for Android with deep ties into Gingerbread. Maybe there really is going to be a Facebook phone. Or maybe it's our dashing good looks and the great conversation we would bring along. We'll know more Wednesday.
