iPint iPhone game sparks $12.5m lawsuit

Apparently more than six million people have downloaded the iPint iPhone app so far. Six million! If you were Carling - the brand it's based on - you'd be pretty happy.

However, the beer brand now has a hangover-level headache, courtesy of a lawsuit from Hottrix, the developer of rival beery app iBeer.

According to Wired's Gadget Lab blog, the developer filed the suit after failing to come to an amicable resolution with Carling's parent company Coors. Both apps let you tip up the iPhone to drink a virtual pint of beer.

"My client ... is really a mom-and-pop company who just wants to protect their intellectual property rights," says Hottrix's attorney Jason Fisher.

iPint is free, while iBeer costs $3 in the US, so the developer is claiming lost sales from the farrago. Watch this one run.
