Apple should add thunderbird+lightning support to at least iTunes on Windows. Not every windows user has Outlook installed.
Right now almost all options to do this include some extra softwares (jailbroken iPhone) or thunderbird plugins and Google accounts. And I may not want my data in Google.
If you do not mind having data in Google read on. Right now I just want to sync Calendar events.
As I need to have data synced I’ll post my findings were. So stay tunned.
All this syncing is dangerous. The iPhone will delete all contacts and/or calendar events on the phone when adding a external sync.
Two solutions so far for Contacts and Calendar:
1- Get your company to install Exchange or one of the Free Software alternatives. And then just add the account on the iPhone and search for info on how to get Lightning to get the data from there.
[New Update 2009-02-15 15:17] There is no need to use the Nuevasync Service
2- This is the one I use. It involves having a Google Calendar account and Sync the iPhone and Lightning there. In the iPhone follow the instructions in the Google Mobile Sync page. To have Lightning use the calendar just add a new Calendar of type CalDAV and in the url put: https://www.google.com/calendar/dav/YOUREACCOUNT@gmail.com/events .
There is no “Sync now” and events will be propagated auto-magically. In my case if I have calendar open on the iPhone and add events in Lightning they propagate in 3 to 5 seconds.
