If you own an iPhone or iPod touch and you are using it as your primary PDA/ diary etc, you are probably aware of some of the limitations in regards to the calendar. One of the most frustrating limitations being that it can only sync up to one calendar. ie iCal or Outlook or Google Calendar. There is however a workaround... a bit of work to set up but a workaround none the less. The basic concept is to have all of your calendars to sync into iCal - and then this iCal calendar will be the calendar which will sync to your iPod/ iPhone.
If your office computer is a PC and you are using Outlook, the easiest way to get Outlook to sync with iCal is to go through Google Calendar. Firstly, you will need to download the Google Calendar Sync software. Once installed on your PC you will then need to sync Outlook with your primary google calendar. You can select whether to sync one way or 2-way and the time interval for sync updates. The great thing with Outlook/ Google Calendar is the fact that it is a 2 way sync, unlike iCal and Google! Once your google Calendar is in sync you then subscribe to it within iCal. The subscription address can be found under your Google Calendar settings.
Now when you connect you iPod/ iPhone your Outlook, Google and iCal calendars will be synchronised!!! Be aware though, that any changes made to your iPhone/ iPod calendar under your Google Calendar sub calendar will not be uploaded to Google as iCal is only 1 way.ie download only (you will need to manually make changes to the Google Calendar using your iPod/iPhone web browser to work around this) . This however is a method for you to keep track of any Outlook, Google and iCal appointments etc...at any one time
