News outlets are reporting that one of the hackers with Goatse Security, the firm behind the AT&T data breach that exposed the e-mail addresses of 114,000 iPad 3G users, was arrested on drug charges Tuesday. According to reports, the FBI had a warrant to search his home in Arkansas, and found the drugs. A hearing is scheduled for Friday.

While this news doesn't change the fact that AT&T has a serious problem on its hands regarding keeping its (and Apple's) users information private, it does cast some doubts over the legitimacy of Goatse Security.

News outlets reported late Thursday that the FBI is now looking into the AT&T network security flaw that resulted in the exposure of more than 114,000 e-mail addresses of Apple iPad users. Apparently the FBI believes the incident may have resulted from a cyber threat, as opposed to a mistake or flaw, making the whole incident sound more ominous.

On Wednesday AT&T acknowledged the breach, saying that it occurred via a security hole in one of its Web sites, and that the problem had been fixed. It was the email addresses of iPad users who had signed up for AT&T's 3G services that were affected. New York Mayor Michael Bloomberg was among those users whose e-mail addresses were exposed, as well as a number of other politicians and celebrities.

In an acknowledgment that it must move quicker to solve the network speed and capacity issues created by the iPhone and increasingly popular mobile data applications, AT&T is reversing course and planning interim upgrades to its network designed to improve performance for 250 million people this year.

Instead of moving straight from 3G to 4G starting in 2011, as it said it would last fall, AT&T now plans to upgrade its current wireless network in certain markets to support the intermediate HSPA+ technology, which is capable of offering 14.4Mbps speeds, twice what its current 3G network provides.

In an apparent acknowledgement that 3G data plans are its future, as voice calling continues to become a commodity, Verizon Wireless took the wraps of its plan to offer Skype Internet calling on its smartphones starting next month.

Skype first unveiled its VoIP application for BlackBerries and iPhones at last spring's CTIA Wireless trade show, and its deal with Verizon marks a major warming to the concept from wireless carriers. Skype first touched off a furor in Europe when Nokia began preloading Skype on its N97 smartphone last year.
