iCal sharing

hey there!

i tried for several hours to share a calender with my brother. he has an iphone 5, i have an iphone 4s. (if that matters..)

the thing is, i can invite him, and he accepts. although, he is allowed to make changes on my calenders, they don't show up on my calender, when he makes new appointments.

we also tried it the other way around: he inviting me to his calender, but i don't even get the invitation at all.

i don't know what else to do.. maybe ical just doesn't work for us 😉

any ideas? or at least another suggestion for a good calender which can be shared..

thank you!!

Anna 🙂
