Well, a country that once banned mobile phones from airplanes is changing its tune (sorry, it's not the US). Mexico has just overturned its ban on cell phones in airplanes law, although it's not all hunky dory. Cell phones suitable for flights within Mexico must be outfitted with special in-flight phone equipment. Until I find out what exactly this "in-flight phone equipment" is, I'll hold my excitement.
I find it interesting that we're allowed to open up our laptops and surf the web in midair, yet the United States still prohibits cell phones from being used once an aircraft is airborne.
