who invented cell phone?

hi i m info dude n today i want to tell u about the invention of cell phone.

On April 3, 2003 marked the 30th anniversary of the first public telephone call placed on a portable cellular phone. Martin Cooper placed that call on April 3, 1973, while general manager of Motorola's Communications Systems Division. It was the incarnation of his se vision for personal wireless communications, distinct from cellular car phones. That first call, placed to Cooper's rival at AT&T's Bell Labs from the streets of New York City, caused a fundamental technology and communications market shift toward the person and away from the place.
