Boostmobile Unlimited Plan.. is it too good to be true?

Boostmobile has this 'unlimited everything' plan that's only $50 a month, and it sounds too good to be true. are there any drawbacks to this cell phone service?|||Yeah I just got off the phone with a rep from boost the only thing is if your using the phone for telemarketing or you make 1,000 personal calls in a day or 2,000 texts over three days (and these numbers were just examples) your service will be cut, its not the definition of unlimited but hey could you really make a thousand personal calls in 24 hours?
