The WWDC was held in San Francisco, the US on Monday and Jobs delivered a keynote speech at the conference. Many tech bloggers have recently pointed out that Jobs looked a little haggard during his speech. For this, an Apple spokesman confirmed that Jobs had fallen ill with a common disease in the past few weeks. But given the importance of this developer conference, he still decided to attend it despite his illness. This spokesman also said that by taking antibiotics, Job's health was gradually getting better.
