Google today launched a new Iphone Web app. This app is really nice as it allows you to use google chat on you Iphone.

Go and have a look:

You must log in with your google username and password and then you will see all your contacts that are online. You can then add a short cut to your Iphone springboard and you are styling.

As soon as you close the safari brower it marks you as unavailible.

Sweet app, now go and enjoy
