For what it's worth: I stopped by the Verizon store in western Cleveland tonight, on my way home from work. The guys there said that they'd been on a conference call last night and were told that the Thunderbolt would go on sale Monday, the 28th. BUT,it would only be available initially online. They said it'd probably be *another* week beyond that until they actually had the phones in their store.
Were they telling the truth? Who knows. They may have been honestly repeating what *they* were told. In any event, my frustration keeps growing and there doesn't seem to be an end in sight.
