Sure, "Super Monkey Ball" from Sega is getting all the press for how incredibly well it is selling, but "iPint" from Carling came right out of the gate as the first marketer to use the same iPhone Accelerometer technology.

As you tilt the phone, much like the Wii remote, the Pint of beer navigates its way around obstacles like bowls of salty snacks -- there's a product placement opportunity within a marketing vehicle -- and down the bar to a waiting patron.

After a tough round of iPint, what's more refreshing than a virtual Carling? The iPhone fills with virtual beer as your reward. Tip the phone and the glass empties realistically. After knocking back a few virtual ones, sending a pint (email to friend to download) is two taps away.

How did I first hear about iPint? Maybe a day after getting the phone, I was sitting in a bar with friends. When the beers came to the table, Rob said, "This reminds me, I have to show you iPint." We may have been drinking a different brand, but Carling was personally advertised, evangelized and passed around between us for 10 minutes while we sipped -- right where we can make a buying decision.

Unfortunately, this application has already become somewhat of a collector's item, as it's no longer available in the U.S. iTunes store. Still, it's a great lesson on how portable the marketing experiences and viral opportunities are in the context of the accelerometer, the phone and a few friends. This is merely for the free version. For $2.99, iBeer takes users deep into the virtual beer-drinking experience. Think for a moment as it ranks No. 11 among paid applications that iBeer is, in-and-of-itself, a brand.
