Martin Cooper, the designer of the first cell phone, joins Sydney from PhoneDog in this special interview. We talked for half an hour, discussing topics ranging from that original cell phone to the mobile market today and the so-called "spectrum crunch" the carriers say we are facing. Marty shared his thoughts and gave some interesting insight on these topics and more. We also allowed our viewers to submit their questions and five were chosen to be included in the interview. Thank you to everyone who submitted a question. Watch the interview to see what his answers were. Some of them might surprise you. The full interview is shown in this video. We'll also be airing segments of it during this week's episode of PhoneDog Live on Friday at 5 p.m. ET on our Ustream channel. Thank you, Mr. Cooper, for your time.
