Apple is due to report earnings today, but many investors and analysts remain as interested in news of the condition of the tech titan - who is a survivor of pancreatic cancer - as they are in the numbers themselves.
"Apple's hedge fund investors are very worried," said a Wall Street source who has spoken with some of the company's stakeholders.
After the conference in June, Apple reps blamed Jobs' weight loss on an unspecified illness that required treatment with antibiotics.
Since then, there's been no update on his health, and company officials now are not commenting on it despite repeated requests.
Multiple sources who have met with - and in some cases even dined with - Jobs in the weeks surrounding the introduction of the iPhone 3G on July 11, said they came away troubled by his thin appearance.
Apple has a history of dragging its heels when it comes to admitting that Jobs is sick.
His October 2003 cancer diagnosis wasn't disclosed until after the removal of a pancreatic tumor. Recent reports have suggested the company knew about Jobs' condition for nine months prior to the public announcement. Web Link
