It's an idea that's as old as iPhone/iPod Touch software version 2.0: the ability to track Xbox Live Gamertags on the Apple handheld. But Nicholas Pike is the first to do it with his iXboxLive application: for 99 cents you can have the ability to view anyone's Gamertag on the go.

The program has an "early" feel to it -- in our tests it's prone to lagging and system crashes, but it does a good job doing what it's supposed to do: displaying players' Gamertags, their Achievements points for each game, and their overall Gamer Score in a touch-screen interface. It also shows when they were on last and playing which game.
