Viewing past events in agenda impossible

[JillB]

I'm looking for a way to sync events in my Google calendar to my phone, events that precede my phone's activation. Up till today, I thought this was impossible, but I've just seen proof to the contrary! My son's phone (a second-hand Nexus S), purchased two weeks ago, has events going back to when he first began using Google Calendar on his PC. My (now-Froyo HTC Desire) phone has never synced anything prior to when I activated it in Aug. 2010, and anything I've found on the subject has always said that this was a Google Calendar failing. Now I'm planning on purchasing a new phone in the next months, and don't want to lose even more information. So my question is this: does anyone know of a way to achieve a sync of all past events? Thank you!
