With two days left in the month,


(AAPL) - Get Apple Inc. (AAPL) Report

says CEO Steve Jobs has returned to work, as promised.

After taking a nearly six-month medical leave, for what was later reported as a liver transplant, Jobs is back and in the office, at least on a part-time basis, according to media reports.

The less-than-transparent details of Jobs' health saga has put the company under scrutiny for not disclosing enough information to shareholders. Critics say Jobs plays a strong role atop the tech device shop and that investors would rightly want to know about any serious health risks he faces.

A week ago, Apple released a statement from Jobs saluting the

1 million

iPhone S phones sold on its debut weekend.

This was the first public comment attributed to Jobs since he left the company in January. The secretive Jobs, who had been recovering from pancreatic cancer,


received a liver transplant two months ago in Memphis.

The news of Jobs' return did nothing for Apple's stock, which ended Monday trading down 0.3% to $141.97.
