My thunderbolt calendar syncs with my gmail calendar but only for the previous 30 days. When I manually sync it it seems to get hung up and the little rotating green circle just stops turning. I want to import events that are in my gmail calendar on my computer for the previous 6 months onto the phone.
We have confirmed with HTC that there is no setting on the device to expand the length of time used to sync past events. We can only recommend that you search on the Android Market for a possible third party application that may allow this function.
