Everything has just randomly vanished? This is including a cantact i added only a few hours ago. The number is listed in my call history but no name? I did uninstall and re-install whatsapp last night and after i noticed i couldnt find some contacts I went into my phonebook and there was a message (i forgot what it said) regarding whatsapp. How do i get my constacts back - especially all my ones saved on my sim? It seems the only phone contacts left is from facebook and old ones saved to the phone (not to my sim). Thanks, EDIT - i just checked whats on my sim people->menu->manage contacts->Import from sim and it appears something has reset my sim? How would this have been possible? Is there anyway of undoing this - just wiped off 10+ years of contacts.
