24 Hours - the thriller drama - aired it' fifth episode of the 2005 season last night. While just one of many similar episodes, it highlighted many of the reasons why a cell phone is not a good idea if you're a "bad guy" and brought ringtones to a prime time TV audience. A mother heard her recently murdered daughter's phone ring and instantly identified the ringtone as being unique to her daughter - one that her daughter had recently paid for and downloaded. While the "bad guys" initially covered it up by claiming that they too had the same ring tone, it's only a matter of time. Given the capabilities of CTU, it won't be long before they identify all of the wireless subscribers with that specific ringtone and realize that the murdered girl's phone was indeed on the premises.
