Thanks to all for your prompt and helpful responses. I checked on the 3 apps recommended in the iTunes store, all 3 have PC versions, but there were several comments regarding problems w/the new OS 3.0. I'm new to cell phones and the iphone and I was just trying to trick it out as best I can b/c it's new to me and exciting to see what I can do w/it. I think I will wait a couple more weeks to let the app/OS conflicts get cleaned up and then I will pick up one of them; they all sound perfect for my needs.
Thanks again.
