Is it possible for two different iPhones to sync and/or vieweach other's calendars? My husband and I would like to be able to do this so when we schedule things we know if there is a conflict with the other person or not. We do not own mac systems just our iPhones.
Yes this is possible. You need to set up a gmail calendar. Then sync both your iPhones to that calendar 2 way. That will show and sync from your iPhones. In gcal you can also add 2 calendars, for example yours could be red and hers blue, so it is easy to see.
