This is one of those programs I wish I had found before I updated to Windows Mobile 6.1. SIM Manager v1.4 for Windows Smartphone allows you to backup your SIM contacts to your phone and vice versa, copying all of your phone contacts to your SIM card.

For those of us who aren't always careful to sync all of our contacts with our PCs and laptops, this program is a life saver. Truly one of those freeware packages that you don't think you need until you need it!
