He said that iPhone 4 users would be given a full refund if they were unhappy with the device, and that everyone who had bought the handset would be issued with a free case.  Jobs said the problems had affected less than one per cent of iPhone users, but that Apple had been “working its butt off” to find a solution to the problem.  “We're not perfect. We know that, you know that,” said Jobs. “And phones aren't perfect either. But we want to make all of our users happy. If you don’t know that about Apple, you don’t know Apple. We love making our users happy.”  Apple has sold more than three million iPhone 4s since the device went on sale last month, but some iPhone 4 owners reported that their handset lost its signal when they held the device in their left hand, thereby covering one of the phone’s antennae.  Jobs said that just 0.5 per cent of all iPhone 4 users – around 15,000 people – had contacted Apple to complain about antenna problems. He also said that fewer people had returned iPhone 4 handsets than returned the iPhone 3GS, the handset Apple launched in 2009.  He also said that many phones, including BlackBerrys, suffered a loss of signal when held in a similar way.  “We love our users, and if we screw up, we pick ourselves up and we try harder,” said Jobs. “When we succeed, they reward us by staying our users. We take this really personally, and have worked hard over the last 22 days trying to resolve this problem. I think we’ve gotten to the heart of the problem.”  Industry experts welcomed the announcement.  “I think most people will be happy with a free case,” said Carolina Milanesi, an analyst at Gartner. “What people have really taken exception to is the way these problems have been handled by Apple.  “It seems the signal issues have been more widespread in the United States than in Europe, and that’s certainly where most of the complaints have been coming from.”
Apple has acknowledged signal problems with iPhone 4, and will give users a    free case or a full refund.
