Yahoo oneConnectUS-based iPhone and iPod Touch users may now download and try Yahoo oneConnect, “the revolutionary new social address book that brings together a user’s circle of friends, their lives, and all the ways they communicate into one seamless, easy-to-use application.”

Yahoo! oneConnect promises to make it easy to stay connected as it allows users to integrate all their contacts and send text and YM messages. The mobile application may also be used to post status and view friends’ updates on Twitter, Facebook, and other social networks.

“The iPhone has ignited and captured the imagination of what a mobile phone can do,” said Marco Boerries, executive vice president of Yahoo! Connected Life.

“The rich feature set of the iPhone enables the best way to experience oneConnect. The powerful combination of Yahoo! Blueprint, the mobile platform, and the iPhone SDK, was leveraged to create this unique experience of oneConnect for millions of iPhone users,” he added.

While the app is supposedly available initially to US-based users, Filipino web developer Mark Castro tried it and liked its interface: “Trying out Yahoo! oneConnect for iPhone. Looks pretty cool,” he said in a Twitter post.

Yahoo! oneConnect for iPhone’s features include:

  • Full-featured address book that integrates contacts from the user’s Yahoo! Address Book, iPhone and social networks.
  • Pulse: A convenient way to see what’s happening on your social networks. The initial version of Yahoo! oneConnect supports networks including Bebo, Dopplr, Facebook(R), Flickr(R), Friendster(R),, MySpace(R), Twitter(TM) and YouTube(TM).
  • Integrated mobile messaging with your friends via SMS and Yahoo! Messenger, including support for avatars, photos, and emoticons.
  • Favorites: A simple way to keep your most important people close at hand to check on status, call or send a quick message or email.

“Yahoo! oneConnect is now available in the Apple(R) iPhone(TM) App Store and is also expected to support additional devices in the coming months,” a press release from Yahoo! said. We’ll see if it will eventually support Palm OS devices.
