Doesn't really matter anyway. If they inventoried those devices and have PINs noted somewhere, a quick call to RIM would render those devices useless to the masses. Short of changing MEID and PINs on the device itself, they won't function normally anymore.
There is a whole cottage industry that does this, just watch ebay and look in awe at the price completely destroyed devices go for. Just like wrecked cars being bought for their VIN.
I have come across a number of devices in end-user hands with modified ESN's and PIN's
It is not terribly difficult to change the ESN of a Blackberry, it is literally a "Find and Replace" like operation and if your a criminal enterprise dealing in volume quite economical given the relatively low cost of the required tools.
The ESN and PIN are just hexadecimal values within the firmware of the phone and modifiable. The only unique identifier of a Blackberry that can't be overwritten is the BSN serial number of the logicboard.
