I believe that the sticky thing that you are referring to is the white sticker inside the battery compartment. Am I right?
The reason that I ask is because i just peeled that sticker out of there only to find another sticker underneath it. The IMEI# and the PIN are the same, along with all of the other information (I.C. #, F.C.C. #, etc.) the only thing that is different is this line:
Patents: www.rim.net/patents K
Patents: www.rim.net/patents G
The G has been swapped out for a K on the newer sticker.
Maybe this doesn't mean anything. I don't know. No where on there, though does it say anything about the phone being refurbished, which I've seen on other stickers.
