Switched from BB to Serve
Just to add data point.
I closed my BB, and switched to Serve smoothly without too much of waiting. Closed the BB over the phone, and got a Serve card preloaded from CVS. Registered the Serve online on the second day, and then the system showed account under review with a successful registration. Waited to call in on the third day, and the rep cleared the pending review status right away. I'm able to shop around with the temp card, and just now waiting for the permanent card to arrive!
