voice message
Joe put out a message that said "all" pilots were getting the blackberry's (for you old folks, that is a personal data assistant (PDA) that is also a cell phone.
The distribution began with PM's, check airman, PIC's then SIC's.
From what I heard from OCC, many times a crew has been put on standby, then they are not able to be reached while hanging out at the beach or where ever. So with the blackberry, it is to take place of personal phones, pagers, etc. It can be used for personal phone calls while on duty (no phone card), but each blackberry has a total of 1000 minutes. Blackberry to blackberry calls are unlimited, any other call is deducted from the 1000 minutes.
Keep in mind, this is info from the OCC, so take it for what it's worth. I have heard it from other sources too.
