DO NOT USE THIS IF YOU HAVE THOUSANDS OF CONTACTS

I actually paid money for this app to create hundreds of bad contacts in my address book. It took several hundred of my contacts and inserted MY address into these records. So far, I have found 6 more sets of dozens of contacts with another persons address added. This app is probably fine if just have a few hundred apps, but I urge you not to run this app if you have several thousand contacts. My iPhone has 64Gb--plenty of room to perform any task. BEWARE.
