I use the google calendar app that was installed on the Ally when I got it. I sync this with the Google calendar on-line. It seems to sync fine, but not all calendar data is in both places. For the last 4 1/4 months (since mid-May) (I got the Ally in late June) everything I need is on both calendars. But before that, the calendar on the phone has some, but not all, data. The on-line calendar has everything for a couple of years. Does anyone know how I can get the old data to stay on my phone?
