I have a blackberry and i downloaded the whatssapp which allows me to speak to anyone else who has downloaded this application. My friend added my number to their phonebook but i dont have his in mine - will whatssapp still work or will i have to put his number in my phonebook aswell?
How will i know when he is now on my contact list on whatssapp - will i get a notification?
