RIM’s legal woes

Most of you who are BlackBerry users have no doubt heard of the legal battle that is threatening RIM’s ability to operate the e-mail functionality of the devices in the United States.

My question: what’s your Plan B if BlackBerry devices become useless in the near future?

My company depends on them heavily. I know there are alternatives, but the thought of throwing away the investment in the handsets, infrastructure, and end-user training gives me indigestion.

Thoughts or commiseration welcome.
