Like the others have said: this is awful. I also had to use Missing Sync for Windows Mobile from the same company, which was just as horrible. They just don't know how to make proper, stable software with a nice user interface that's actually... well, usable.

If you're looking for a nice iPhone archival (SMS etc.) app that does everything this piece of crap does, for half the money, get PhoneView. Was part of the latest MacHeist bundle. About as nice and even cheaper: MobileSync Browser.

Whatever you do, just avoid this junkware like the plague.
