Mix: TechTool Protogo, Apple probe, Nano noise, iPod phone

Micromat has released TechTool Protogo, a Mac OS X application that lets a user “easily turn an old iPod, a flash drive or other similar device into a bootable diagnostic tool that contains several of Micromat’s utilities.”

The Wall Street Journal reports that Apple’s internal investigation into backdated stock options focused on two former executives—former CFO Fred Anderson and former general counsel and board secretary Nancy Heinen.

A number of second-generation iPod nano owners are complaining of high-pitched whining or buzzing sounds coming from the players. Owners of all models—2GB, 4GB and 8GB nanos—have reported the noise.

According to a recent survey by Solutions Research Group, an iPod phone could have the “potential to increase Apple’s customer footprint substantially. Currently just over 20% of Americans 12+ (about 50 million) own an Apple product—within 18 months of the introduction of a new iPod phone, Apple’s footprint can increase to over 30%.”
