Good news for anyone who wants to doff their Sprint shackles but was unwilling to pay an eye-gouging cancellation fee. See, Sprint's just raised their text-messaging fees to $0.15 per, which constitutes a "material change" to your contract. Any time there's a material change, you're capable of canceling your service without facing a fine.
Good news for you, oh disloyal Sprint customer.
