We bought cheap phone for Pinoy Jokes and Funny filipino SMS Text TXT Messages blog. It is a Nokia 1661 decent enough to receive txt messages contributions from my blog visitors. My old Sony Ericsson k770i fucked up when we fly from Manila to Singapore. Maybe the "static electricity" thing killed the phone. But im pretty sure that i turn my phone off. So as a precaution, better to remove your phone's battery before boarding the plane.
