I just updated to the new att firmware on my galaxy s2 and the calender was fine for about a week then just now as I was looking at it is deleted everything. I have alot of important stuff on it. How can I get it back? It happend when I hit the button to see diferant views (new button for the update) and it just cleared it all. Please help I need to find this stuff. I did back up with kies before the install but it was fine a secound ago.
