I noticed this little update yesterday when I was pricing out a Tour for a friend but I did not understand what it meant then. It looks like Verizon has updated their website with their new Buy One Get One free free offer. This time it is running until October 10th so get a move on it. 
The other main change is that the second device does not need to be a BlackBerry. It could be another phone or a netbook or broadband wireless card. This should make quick work of Verizon’s BlackBerry Tour inventory.
