At our business, we have blackberries, iphones, and android phones. Most of the android phones have 2.2 on them, but a few of them still have a little older version on them. My question is this: can you sync shared exchange calendars to any/all of these devices? if so, does it require third party applications? I have read that iPhone requires third party software for shared calendars. If third party software is available for these devices, does anyone have any suggestions for any of these types of devices? Thanks in advance for any answers/comments.
