Can I set one up with the ability to send from the bb and not receive any messages to the device and check it on my own? I have a .mac account and prefer to use it but would like to sent messages from the bb but not receive them as they alert me at bad times while I need to receive urgent messages from my verizon acct.
Thanks
Marc
