Want to be asked to"switch on" that mobile handset on our next flight from or to Australia? You may be in luck if Qantas' public in-flight wireless trial bears fruit soon. While the FCC still cannot determine whether cellphones cause interference with ground-to-flight communication networks, Qantas is barreling right ahead with a trial. We have to ask: FCC -- what is the deal? C'mon guys -- we're sure some folks have used cellphones while flying and no planes have fallen from the sky as a result. It's been years and years and no movement. Sigh. Anyway, another kinda-important detail from Qantas: the in-flight mobile trial is for wireless email and text messaging only. The airline operator doesn't want rude fliers screaming into their handsets just yet.
