I have accidentally deleted my iCloud contacts. I try to import in vCard of my contact address (6Mb file) but it could not import. Is there any way to reinitialise the iCloud to sync my iPhone contact list into the iCloud? The last time I tried that on my iPhone, my contact got wipe out, I have to restore it back from my backup. Currently I am setting my contact to be default at iPhone in case my contact got wipe out again (previously was iCloud as default). Any help?
