It is always a troublesome job to remember the birth day of your pals and family and wish them on time. At least, for me, it was. google calendar is what I use for keeping track of events and get alerts on my cell phone so that I wont miss any. I have always searched to find a way I can get alerts of birthdays to cell phone by integrating orkut birthdays with g-calendar, followed up the same request with google communities, but never found a way to get this done.
Finally google has come up with a solution to this, you can see a link
Just below the ‘upcoming birthday’ section in your prifile page. This takes you to the google calender and it’ll have all the orkut birthdays marked in the calender. Now the most important part – getting alerts of google calander events in your cell phone. go to http://www.google.com/calendar >> login using your gmail username/password >> go to settings >> mobile setups. Start by selecting your country and then enter your phone number and carrier. A verification code would be sent to your mobile prior to activating this facility. Finally enter the verification code sent to your phone. They says there can be charges for incoming message ( google doesnt charge you for this service), but I’ve been using this without spending a single buck over a vodafone India connection. Cheers.
Edit: Looks like this is no more a service provided by google, but hopefully will resume someday
