content: It's even better because you can tell the people who did not read the article and are jumping on the "fuck T-Mobile" bandwagon here in the comments. The tethering limit is clearly stated. You can use unlimited data on your phone, 7GB tethered. If you're using an app, ROM, or anything else to bypass that limit, you're breaking the contract and terms of service. They're well within their rights to revoke your access to their network. Edit : Oh shit, did I hurt fee fees or something? A contract and it's terms are laid out clearly. If you violate those, you can and will be penalized for it. That's how business works everywhere.
