On Saturday night, the well-known hacker Mathieu Hervais posted on his Twitter that he had found a way to exploit Sony PlayStation 3 firmware 3.56 although he refuses to release the details, as not to anger Sony.

Says Hervais:

I hesitated a lot before tweeting about it, but a bug allows exploiting metldr, the bootloader and 3.56+. I don't intent to ever unveil it.

So much for "unhackable" ps3s though....

The hacker will not unveil the exploit, but says "this wasn't about getting attention at all, or fame, this was just done so the right people know this bug is there for the finding."

Hervais' decision comes after Sony has taken custom firmware creator Geohot to court, as well as subpoenaed IP addresses of other hackers and even casual visitors of Geohot's site and YouTube account.

JD Power's latest call quality study has been released this week and unsurprisingly Verizon once again tops the list, for the 13th straight time.

The carrier had the best call quality in the northeast, southeast, southwest and west and tied with AT&T in the mid-atlantic.

In the north central, US Cellular held its annual lead.

The rest of the major carriers were mostly mixed bags, but T-Mobile and AT&T had some terrible scores in some regions. Sprint remained in the middle for all regions.

T-Mobile was by far the worst in the northeast while AT&T took home the lowest score of the study for its showing in the west, anchored by infamously bad coverage in San Francisco.

Interestingly, the company says smartphone users and frequent texters encountered more problems than average, around 13 out of every 100, while average users had 11 problems.

Apple's updated MacBook Air line has quietly become a hit, with the company having shipped 1 million of the notebooks in the fourth quarter.

The figures come via Concord Securities analyst Ming-Chi Kuo, who says recent checks in Asia imply that Apple shipped 1.1 million units for the three months ended December 31st, 2010.

If accurate, the numbers will indicate one of the strongest Mac launches in history.

Furthermore, Kuo says the Air are now selling at a 1:2 ratio to the MacBook Pro laptops, Apple's best-selling.

Kuo says he expects Apple to "set a new Mac sales record during the [upcoming] quarter."

According to multiple reports, large retailer Best Buy may be ready to give iPads to all on-floor sales associates.

Best Buy has about 1100 stores in the United States.

Forbes, via AI says:

A source with knowledge of corporate mobile device deployments has told Forbes that one of the 10 largest retailers in the U.S. will soon distribute iPads to all its sales staff. The source noted that the retailer in question operates 1,100 U.S. stores, making Best Buy, which had 1093 U.S. stores as of September 2010, the most likely candidate.

Best Buy and Apple have a long retail history and the retailer is set to begin selling the iPad 2 on March 11th.

The retailer has 180,000 employees, although it is unclear how many are on-floor sales staff.

Associates will likely use the iPad for a new point-of-sale and inventory management system.
