Finally! Yahoo Messenger is now available for free on the iPhone. It may not be the most popular instant messaging program out there, but users can now run a tailored version of it on the iPhone. You’ll be able to do some of the same things enabled for desktop computers; which should be no surprise to anyone having used it. Sadly though, just as with other apps on the iPhone, it won’t run in the background fully. Instead, it will keep you logged in for ten minutes while displaying you as idle to other people. Once the ten minutes are up, you’ll need to log back in order to stay active. Anyway, they at least put some effort into the look and feel of the app.
