Have you ever thought about creating an excuse to be late? Well now your cell phone could make that a lot easier with new software that generates fake background noise. Different backgrounds can also be assigned to different phone numbers so that they automatically kick in when a certain person calls. The software can even create the sound of another phone ringing to provide a handy excuse for cutting short a call. Now, please be aware that this is not something I personally advise as I believe it is helpful to live in full integrity, but I posted it as many people might start pulling this trick on you.
