Apple settled a class-action lawsuit brought by users of the iPhone 4 that contended antenna issues caused some them to lose their wireless connection.

“This settlement relates to a small number of customers who indicated that they experienced antenna or reception issues with their iPhone 4 and didn’t want to take advantage of a free case from Apple while it was being offered in 2010,” Apple spokeswoman Natalie Harrison told me on Saturday.

The settlement gives users a free iPhone Bumper case or $15.
