Alternative to iOS Cal with CalDAV support

Hi

I am looking for an alternative calendar application for my iPhone. I tried Sunrise but the problem is that it does not support CalDAV. I have all my schedule synced with Fruux so I need an application which supports CalDAV.
Any suggestions?
Thanks! ;-)

Fantastical for iPhone supports CalDAV:

It works perfectly. Thank you very much!
Btw where is the thank you button?

On the top right side of each message you'll see two buttons -- the "add to reputation" (a "thanks" button, essentially) and a "report this post" button. Try to press the right one.
