Hands-On Google Talk for iPhone (Verdict: Stick with Installer.app)

Google's brand new Gtalk webapp for the iPhone is as crappy as I expected it would be. It has a nice design, and sending messages was easy, but at the end of the day it's still running in Safari—which means if you get a call you are signed out of chat. And unlike other web-based IM apps, Gtalk doesn't work in the background, so interruptions as simple as going to the home screen sign you out too. Also, there are no preference settings, so you are stuck looking at your whole contact list, online and off. Gtalk's AIM support is also curiously absent from this release. In short, this program sucks. If you're looking for a solid IM solution before the App store opens, I strongly recommend Agile Mobile's AM client recently released on Installer, which I've been playing around with.
