If I add a photo in contacts (over homescreen contacts icon) it disappers after pressing home button. If I do same over phone icon it isn't visible if I go in contacts over homescreen contacts icon and stays only till next synchronisation or reboot.

The problem didn't appear earlier. My iPhone has FW 1.1.4 but I heard of someone with same problem on 2.2. I did already a reset.

Is there a solution?
