This question is for the legal experts.... I'm a Sprint customer and the vanishing keyboard is driving me crazy! The patch for this fix has been available for months now but Sprint or Verizon will not release the update necessary to fix this problem. It seems to me that they are purposefully crippling the product (iMO, I think they are purposefully trying to create negative experiences with Windows Phone to make it a 2 OS ecosystem.) and crippling devices create a negative experience. It doesn't make sense that Apple can update without their consent but no one else can. So my question is, as consumers, can we bring legal action against the carriers if they are purposefully crippling devices?
