A little bit different from my normal posts, but I've found a fix that's worth sharing.
So using iphone for multiple calendars...
[Note added later: the most effective method for this is to use MobileMe, but I'm way to cheap to pay for that. So using iphone for multiple calendars for free...]
I have a PC with the usual Microsoft stuff at work. And a Mac with iCal at home. Switching on the calendar element of the Microsoft Exchange stops exchange of data with ical and removes the iCal data. So how do I get both my calendars on my iphone?
This isn't perfect but it seems to work (NB I've not done steps 2 or 3 yet, that's a task for tonight!). The trick is to use an internet based calendar. I've gone for Google Calendar, but I've heard you can do similar things in Plaxo.
Step 1: Sync your Outlook with Google Calendar.
Nice easy instructions here.
Step 2: Take the feed from this Google Calendar and subscribe using iCal.
Instructions here. As noted above, I've not tried this yet, so fingers crossed for this (& particularly step 3!)
Step 3: Sync your iphone with your mac as normal
Fingers firmly crossed.
Not perfect especially as the Google Calendar to iCal sync is unilateral. But a good start nonetheless.
[Note added later: this all works just fine. Just a pity that iCal doesn't sync back to Google Calendar. You can buy this if you want to solve that problem]
