Yep, I saw this last night. I pressed the tab and got the same screen as the OP with the swirling circle going on forever. In fact I fell asleep with it spinning and woke up this morning and it was still spinning. Luckily it was plugged in.
I'd like to know why it's there given the fact that VZW doesn't even sell the PlayBook and the only connection they have with it is via the Bridge which I'm sure they hate.
I have two PBs. One using my corporate email address and one configured with one of my personal email addresses. The corp PB does not have the Verizon tab, while my personal PB does. The only reason I can determine that my personal PB sees the Verizon tab is that my personal PB is configured to use the same email that I use for my family's Verizon phone account. (my BB is a corporate device, so that doesn't factor in)
