Verizon was the first carrier to come to Samsung's defense in the company's patent dispute with Apple, but it's not the last. As Reuters reports today, T-Mobile has now also sided with Samsung in the lawsuit, stating in a court filing that a sales ban on certain Samsung products would "unnecessarily harm" the carrier and its customers, and that, "at this late date, T-Mobile could not find comparable replacement products for the 2011 holiday season." The carrier also noted that its ads also "prominently feature" some of the Samsung products in question, and that those investments "cannot be recouped easily." As for the case itself, the next big date is an October 13th hearing on the injunction request.
