yeap, wazapp working for you, no doubt about it

but, as for contact sync, its a bit trickey..I got one contact, which previously I forgot to put "+" in the contact book, didn't appear after I perform "Sync Contact" in Wazapp's Contact list,
but this contact did message me through WhatsApp before.
Then I go to contact book, add "+" to this contact's number, and "Sync Contact" again. Then this contact appear on Wazapp's Contact list.

Not sure which side at fault for this problem
