Pining for PIN wants to know:

How do I create and send a PIN-to-PIN message in the API v4.0 ?

Guru PINs back:

Sending a PIN message is really no different than sending an email message.  The only minor change is that when you create the message, the recipient must use the class net.rim.blackberry.api.mail.PINAddress.  When a message is created you just supply it with a PIN address and the system realizes that it has to send it using the PIN protocol instead of email.   

Roaming for a reply inquires:    

Do you know how to tell what PRL is loaded on a BlackBerry device from the device?

Guru:

For those novices out there, PRL stands for "Preferred Roaming List", and it is used by the phone to locate different cell systems. This simple question needs only a simple reply: from the Phone application, dialing #HELP* will reveal another screen which shows the PRL Version.
