In a recent column, I talked about synchronizing your Web bookmarks, but what do you do when all your appointments and contacts need to be synchronized across your laptop, your cell phone, your Palm Pilot or other favorite digital organizer?

You may want to check out SwiftTouch. At this site, you can download free software-called Swiftsync-onto your computer, onto your Web-enabled phone and even onto your organizer. Then you upload all your data back to your secure account on this Web site. Data can include phone numbers, e-mail addresses, mailing addresses and appointments. The SwiftTouch software then synchronizes all your data together.

Now you don't have different information on different communications tools. The SwiftTouch site also acts as a backup for your data so if something crashes, you can go back online and download everything safely onto your devices.
