Ok, so I finally jumped on the boat and dumped my Blackberry for a new Iphone.

I need some input from you apple guys and long time Iphone users.

I rely on my calendar pretty heavy, and the biggest drawback I have found so far is that I can't accept incoming invites from my fellow Blackberry users or outlook users in the office. The basic calendar on the Iphone also won't set a reminder for me by default. I can accept the invitation in Outlook and sync it to my iphone, but, There are many days I'm not even in the office and would like to respond to meeting invites right from my phone.

I'm sure there's an app for that =) I just haven't had much luck finding one.

Ideas ?
