Now this is a surprising step from RIM. They has just put up a knowledge base PDF file detailing:
Steps to take before selling, or after buying, a previously owned BlackBerry smartphone. (cropped screenshot of PDF below)
It is nice to see that RIM is making an effort to help users who have bought a used BlackBerry or are selling their BlackBerry. The document is pretty good but it is inherently flawed.
Personally I wish they would just make it easier to remove the association of a BlackBerry with a BIS account without having to call them or enter in another device. This causes hundreds of tech support calls
The other problem is that RIM does not make an easy process for reseting the device to default to remove an IT policy after it has been purchased if the device was previously associated with a BES. Now this problem will be exacerbated by the fact that BlackBerry Unite also adds an IT policy to devices.
