My iPhone had terrible service yesterday, so I called AT&T, they suggested that I get a new SIMs card. I did and they kept my old one after telling me that it contained absolutely no data/information. I got back to my office and my iPhone synced automatically to my network (Office365.com). Later in the day I noticed that some of my contacts were missing. I began looking for them in Office365.com contacts and they were missing from there also. Does anyone have any suggestions how I can find these missing/deleted contacts.
