If you have an iPhone and you work at Penn State I am betting you've been trying in vein to get your Oracle Calendar to talk to one another without jumping through major hoops. I know it has been one of the biggest frustrations for me over the last couple of years. That is a thing of the past with the new $14.99 iPhone App, Tool+Cal+Sync (opens App Store). Yes it costs money and yes I paid for it out of my own pocket, but if this works I am more than happy.
I was shown this little gem by Chris Hubing in ITS' Emerging Technologies group. He has a great post up over at his blog (dude, get an offical PSU blog!) where he lays out all the settings. One word of warning, it works very slowly on my iPhone ... I am guessing b/c I have a large number of calendar entries. But it does work -- as a matter of fact it is working its magic right now!
Tried, but it was furstrating. I prefer Bento from Filemaker which has recently been released for the iPhone. See
