I was setting the Toodledo calendar on my iphone and got a question due to differences between the help files and the tools section.
On the help:
Go to Apple's "Settings" app.
Tap on Mail, Contacts and Calendar.
Tap on Add Account.
Tap on Other.
Tap on Add Subscribed Calendar.
Type in the url noted on our website: www.toodledo.com/id/your_id/ical_live_apple.ics
