Once you get your hands on the iPhone, there's no doubt you'll want to try new iPhone optimized applications available out there. I found a few good sites (Download Squad, Webware) already tracking down new apps for iPhone owners. So what's out there? You'll need to install Safari 3.0 to try them out on your browser. An no, you don't need the iPhone to get a preview. Really.

 Here's list of the applications available so far:

• iPhone Digg: Scroll through Digg stories
• iPhone Chat: Let's you chat with friends on AOL
• Gas.app: Find cheap gas by zip code
• iActu: Read your favorite newspaper on iPhone
• One Trip: Shopping list builder
• Go Movies: Look up movie listings on Fandango
• iPhone News: Get the latest Yahoo and Google news
• iPhone Feed Reader: Displays your favorite feeds on iPhone
• iTweeter: Interface for Twitter
• YouTube: Interface for YouTube
• Bravetail: Wordpress mini-blogging service for iPhone

You can find a more extensive list of iPhone applications over at iPhone Application List. It's a good site to bookmark. Playing with these widgets really makes me want an iPhone even more, though. Sad.
