The legacy company that made Blackberry phones is about to kill them off by shutting down the server they are tethered to.

Since few of those phones remain in use, I think it is legitimate to want to save money by not running a server for them. However, it is not right to stop people from modifying the phones' software so they can talk to some other server -- or modifying the Blackberry server code to give them something else to talk to.
