What is JAJAH? It's a service that allows you to make phone calls for cheap (and sometimes, free). You input your phone number, then type in a friend's. Your phone will ring. When you pick up, it'll connect to the person you're trying to reach. Why bother with the roundabout way? Well, it's really cheap: only 2.8 cents within the US, and if you're talking to a fellow JAJAH member, the call will be free. (JAJAH also offers 21 minutes of free talk time for signing up.) It's not the elegant VoIP functionality we've been promised from Sony, but it's an interesting alternative.

While we wait for Skype to appear in a future firmware revision, we'll play around with JAJAH. All that's needed is the internet browser--no homebrew necessary. Point your browser to mobile.jajah.com, and log in with your free JAJAH account. Your contacts will appear as clickable links. When you dial in, your phone will ring, allowing you to talk to your friend. If you're talking to a fellow JAJAH member, it'll be free.

To make the most out of the service, you should probably upgrade to the latest firmware, and take advantage of T-Mobile's free Hotspot service. Then, you'll be able to browse the web, play games, and make phone calls from PSP, all while grabbing your morning coffee at Starbucks.
