i would like to buy BLACKBERRY PASSPORT OR PRIV ....

Basically I would like to ask about the passport will continue the support with the BBOS or will there ever be problems?

Do I have gmail to be able to transfer contacts, groups etc to the device? Will they see them to be called and called?

FACEBOOK, INSTRAGRAM, VIBER, WHATSUP will i have? Or should I go to PRIV?

Can it cover these passport needs?

Thank you very much
