Great thread, this is always a topic of controversy for us.
1. Send the wipe command
or
2. Set PW and lock handheld with a message to call a number.
Anyway, I have question about some of your comments:
Some of you spoke of deleting accts from BES. What if you re-issue a new BB to the user. Would you not send the kill command, then activate the new device to the existing account?
This is our protocol, even if the lost/stolen BB is not communicating with BES. We do have a 30 min PW lock policy on our BB's, so hopefully the lost/stolen BB is PW locked.
