Google Talk Optimized for iPhone

Google has optimized Google Talk, its web-based instant messaging program, according to the company’s Mobile Blog website.

To send or receive instant messages an open instance of the phone’s Safari browser must be running. Switching to another browser window or application will change your IM status to “unavailable,” but you can select from a quicklist of the people you contact most, search your contacts, and manage multiple conversations. The company said it designed the iPhone optimization to closely resemble its desktop application.
