this one is excellent. I will tell you how to make automatic facebook status updates and tweets using google calendar.

what you need:

• properly setup google calendar and ical sync
• properly setup iphone syncing with gmail and google calendar
• properly setup ping.fm account

ok; so….

there are two methods here; each with two parts.

one isnt very good, it basically sends the google calendar reminder email to ping.fm. im not sure if you will need it, but ill scope it out just incase you do. the other method takes the google calendar rss feed and emails that to ping.fm

• open google calendar
• make a new calendar. I called mine ‘tweets’
• make it public if you want..
• goto settings for that calendar.
• goto ‘notifications’
• make it read ‘by default remind me via email 1 minutes before each event’
• goto ‘share this calendar’
• in the email address field, type in the email address you get by going to ping.fm/email
• make sure you dont let gmail send that email address an invite..
• goto ‘second step’

• open google calendar
• make a new calendar. I called mine ‘tweets’
• make it public if you want..
• goto settings for that calendar.
• grab the xml feed for your new calendar

now; you have to choose between sending the feed to ping.fm, in which case you can get all your social networks updated at the same time, or using something like twitterfeed to send it to ping.fm [which is broken just now] or just sending it from twitterfeed directly to twitter.

• if you want to add it to twitterfeed then go to twitterfeed.com and setup an account there and add the feed.

I used twitterfeed – it has a lot more options and is a lot more customisable; its not as good as I wanted, but at least I have put you on the right path..

now; go ahead and make calendar events in your new tweets calendar. they will appear in the social networks that you have enabled in ping.fm. it works for recurring events too. so I can now have a tweet that goes out every tuesday saying ‘buy my stuff’ or whatever.

if you want to set auto tweets from your iphone; make sure you go to

• m.google.com/sync

in your phones browser and check your new calendar so that you can add events..
