Okay, this might be a stupid question but several of my friends are giving me their PINs. How do I start a message with them using their PIN? What program do I use?
Use blackberry messenger. First you need to invite them using their pin # to be one of your contacts.
Once they accept the invite and you confirm you will be able to start chatting with them.
