Be very careful

The first time it used this app it worked very well and I was able to delete all of my contacts from my iPod touch. The second time I used the app I furst used it to delete my contacts from my iPod touch and then connected to my computer for a sync operation. I had set the preferences for the computer to overwrite the data on the iPod. Unfortunately, all of my contacts were deleted and without going to the recycle bin. Fortunately I had a backup or I would have lost 10 years worth of contact data.
