AOL says its SHOUTcast Radio app is now available for the iPhone and iPod Touch via a free download from the Apple App Store. The Time Warner unit demonstrated the app on the devices at last week's Macworld show in San Francisco.

The Internet-based network provides access to 26,000 radio stations via Wi-Fi, EDGE or 3G. On the iPhone or iPhone Touch, you can use the built-in accelerometer control to change stations by shaking the unit.

AOL got its instant messaging act together on the iPhone too. It recently announced the development of a version of its ICQ client for the iPhone and version 2.0 of AIM for iPhone.

ICQ will offer real-time IM communication, Contact List access, and the ability to hold multiple IM conversations with anyone on AOL’s worldwide IM network -- whether they are on AOL, AIM, .Mac or MobileMe -- via IM or SMS. Just swipe your finger on the iPhone’s screen to switch between conversations.

AIM for iPhone 2.0 adds SMS notifications to let users know when they receive new IMs, even when AIM is not running. In addition, users will be able to access contacts in their device’s address book directly from AIM and send an IM to a contact’s screen name or an SMS message to their phone number.
