Do you wish you could make calls from 30,000 feet off the ground from your mobile phone onboard a private jet? Well now you can through your Android smartphone, thanks to the most expensive app to hit the Android market. The app, called SafeCell, by ASiQ Limited Australia is said to be “the world’s most affordable in-flight mobile phone solution for private jets”. While conventional technology usually costs between $350,000 and $500,000, the app brings it to you for a measly $12,500 ($17,500 for a multi-channel license). The app will be functional in the United States, alongside other select countries.
