So, Phone Phreaking, beginning in the 1950's with Joe Engressia's stumbling upon
the problem with 2600 hertz calling, has evolved over the years along with new technologies and companies. Along with this evolution has come new breeds of Phreakers, from Cap'n Crunch using a simple whistle, to Phiber Optik (real name Mark Abene) a forerunner in code hacking for long distance calling. These problems stemming from Phreaking have slowly been eliminated, yet as technology advances in the telecommunication world, you'd expect Phone Phreaking to evolve with it.
