Swim is a cool new utility that lets you automate data synchronization between internet servers and your Symbian S60 powered device. Google Calendar, Mobical, Zyb, Ovi, and any other server with SyncML support can be synced with your phone using Swim. Timer settings allow you to sync your data every 15 minutes, every hour, every 4 hours, every 12 hours, daily, or weekly.
Be aware that Swim comes with special installation instructions; however, they are simple to follow. It's well worth it to be able to sync your data on autopilot!
