At age 49, Junior Alexander Guy got his first cell phone last month. The calls started immediately.

Strangers called at all hours. Some were insulting. Others angry. Sometimes, they threatened him.

"You murderer!"

"You deserve to die!"

By Day 2 he figured out what was going on: T-Mobile had given him the phone number formerly used by George Zimmerman, the Neighborhood Watch volunteer who fatally shot Trayvon Martin in February.

The number — 407-435-2400 — was the one Zimmerman spelled out to a police dispatcher in a recorded call the night of the shooting that has since been widely circulated by news organizations and is available on the Internet.
