TWO BERKELEY, California, teenagers allegedly tried to rob a woman of her iPhone last week but gave it back because it wasn't modern enough, police said.

The April 4 robbery was among a series allegedly committed by the two 17-year-old boys, who were arrested and booked into Juvenile Hall on suspicion of armed robbery after they were tracked down in Berkeley, police said.

One of the teens apparently held up the woman at gunpoint. He demanded her iPhone, which she handed over, police said. But when the teen found out it was an older-generation model, he returned it to her, police said.

That robbery happened several minutes after police responded to a man who had been robbed of his laptop and iPhone by two teens in his home, police said. The thieves kept that iPhone, police said.

Berkeley police nabbed the teens about two hours after they handed back the iPhone, police said. After three reported robberies in Berkeley, police spotted a vehicle the teens were driving and notified authorities that the teens were found in possession of the stolen items from the earlier robberies in El Cerrito, police said.

The teens later confessed to committing other robberies in Emeryville and Oakland, police said.
