T-Mobile was the target in a year long hacking operation used to monitor U.S. Secret Service email, obtain customers' passwords and Social Security Numbers, and download candid photos taken by Sidekick users, including Hollywood celebrities.

The culprit, twenty-one year old Nicolas Jacobsen, had been quietly charged last October after Secret Service helped investigators link him to sensitive documents circulated in underground IRC chatrooms.

The informant also obtained evidence that Jacobsen had access to T-Mobile's 16.3 million customers, including many customers' Social Security Numbers and dates of birth. Additionally, voicemail PINs and passwords that provided customers access to T-Mobile email accounts were compromised. He did not, however, have access to credit card numbers.

This was all part of the Secret Service's "Operation Firewall," aimed at cracking down on Internet fraud rings which let to 19 men indicted for trafficking stolen identity information and documents, and stolen credit card numbers.

T-Mobile responded to the claims yesterday: "To our knowledge there have been no repercussions to any of our customers," said Peter Dobrow, a T-Mobile spokesman. The company said it and the Secret Service are still investigating the second incident to determine whether other customers were affected. "We are not aware of any other device that was accessed in that manner," Dobrow said. "The hacker had access to very limited information, but it is still under investigation."

Tmobile doesnt keep credit Card information on file, the customers who information that was accessed were contacted by Tmobile personally and so far there are no reports of any customers having problems with identity theft or fake credit cards being made in their name.
