Its been three months since the Nexus 7 was supposed to arrive on Verizons LTE network, but Verizon is still refusing to activate the device. Now, the company is blaming Google and device manufacturer Asus for the delay getting the tablet certified. Verizon told Android Police that after it discovered a systems issue during the certification process, Google and Asus actually asked the cellular carrier not to certify the tablet for Verizon LTE until an update to Android 4.4 could arrive.
