The calendar on the s3only syncs back 30 days bot syncs forward fine. I use GOOGLE calendar. I have tried delete of calendar, reinstall, delete data, resync..nothing..I have on my iPad the calendar goes back to 2007, on the computer it goes back to 2007, on my old evo 4g the calendar goes back to 2007.

I have talked to Sprint, Samsubg, Google, and Best abut Geek Squad as well as their mobile department. NO ONE has been able to figure out why it won't sync backward. Best Buy even took a new phone out of the box and activated it, tried to sync my calendar, same thing happened.
