Previously available by invite only, mundu is now available to the rest of us.

It allows you to use your Yahoo!, Google, MSN, and AIM accounts with ease.

Emphasis on “ease.” I was up and running and logged in on my iPod Touch in under a minute. Very, very simple stuff here.

You’re able to be logged in to more than one service at a time and you can make your own status messages and remove contacts directly. It also handles smileys.

Best of all, there’s nothing to install. Just point your iPhone’s browser (iPod Touch, too) to iphone.mundu.com and you’ll be good to go.
