Hands-On Google Talk for iPhone

From Gizmodo -

The new Gtalk webapp for the iPhone has a nice design, and sending messages was easy, but bottom line it's still runs in Safari and doesn't work in the background — which means incoming calls and other interruptions such as going to the home screen immediately sign you out.

There are also no preference settings and no Gtalk AIM support. Meaning, the program sucks. If you need a solid IM solution now try Agile Mobile's AM client (recently released on Installer) instead.
