A Michigan woman who lost her iPhone in a mugging on Michigan Avenue is getting a new one from the organizers of the Rock 'n' Roll Half Marathon she was in town for.

"I started crying," said Tammy, the 51-year-old victim, who was back home Tuesday when she learned of the gift. "I'm like ... oh my gosh … I'm so grateful."

The robbery happened Friday night and included another visitor to Chicago, a 15-year-old girl who tried to help Tammy while she was getting robbed by a group of teens and got punched by one of them.

Christine Lock-Bachman, who works for the Half Marathon, said she saw the Chicago Tribune's story about it and told her supervisors.

"I told the people I work with at the race what happened ... right away, without any hesitation, they said: 'We’re getting her a new iPhone,' " Lock-Bachman said.

Tammy said she didn't let the robbery ruin her weekend and still had a great time in Chicago. They were even able to return a lost iPhone themselves.

Tammy said that after she, her sister Rhonda and their 70-year-old mother were robbed, they continued on with their sightseeing with Rhonda's husband Jeff. They left Navy Pier around 10 p.m. and headed to a grocery store when Jeff saw an iPhone lying on the ground and picked it up.

Jeff went to turn it over to the store worker when a woman with a child in a stroller said she had dropped it outside.
