Iphone 4s losing new contacts
My iPhone 4s is only a week old. I imported a bunch of contacts from Yahoo! and they're all just fine. But I've put in a couple of new ones in the last week. Just earlier today, not associated with any event, all the new contacts disappeared. If they were phone numbers in my recent call list, instead of having a name, it just shows the number, as if the contact entry has disappeared.
Also, this is the 3rd time I've had to tell Siri who I am. Is anyone else having this problem. If you are, do you have a solution to make it stop?
Thanks,
