Apple will end its free iPhone case offer at the end of September, saying that the antenna problem was smaller than originally thought.
In July Apple CEO Steve Jobs told a US press conference that the company will offer a free Bumper case to all iPhone 4 buyers as a way around the much-reported signal problems.
That said, the company will still offer to provide a free case to the "small percentage of iPhone 4 users" who need one.
"We now know that the iPhone 4 antenna attenuation issue is even smaller than we originally thought," Apple said. "A small percentage of iPhone 4 users need a case and we want to continue providing them a Bumper case for free."
