Tracfone Wireless v Thomas et al.
Some stories on various blogs reported a judgment against the defendant, who was allegedly unlocking Tracfone prepaid handsets and reselling them for a profit.
Since there's no information about whatever reasoning the judge used, I had a look in PACER -- turns out it's a default judgment, so not much to go on other than whatever theories the plaintiff's attorney decided to claim, which appear from some cursory skimming to be a shrinkwrap license and DMCA.
The case is 3:07-cv-01495, Tracfone Wireless, Inc. v. Thomas et al. If anyone's interested in not racking up $5 to their PACER account, you can grab my copies:
