ListPro can synchronize a particular file with a Windows Mobile device, or with an iPhone, but not both at the same time. You will have to switch synchronization for your file from Windows Mobile to iPhone.

1. Open ListPro
2. Click Synchronize -> Synchronized Files
3. Click Windows Mobile
4. Click on the list file(s) that you want to switch, then click Remove. This will not erase your file - it will move it to your regular My Documents folder on your computer.
5. Close the Synchronized Files window
6. Click Synchronize -> Enable Sync, then choose iPhone
