There's a curious little piece over at TUAW.com. Apparently American soldiers in Iraq and Afghanistan are being supplied (on a limited basis) with iPods equipped with special software that will help them communicate in Iraqi Arabic, Kurdish, Dari and Pushto. The software will handily "display a phonetic translation, speak a phrase through an attached speaker, display the phrase in local writing, or demonstrate hand gestures that are common in Arabic." Surely this is a candidate for our once popular piece: 10 Unexpected Uses of the iPhone.
