I was under the impression that the Verizon LTE phones had their CDMA authentication modified to use the SIM card for authentication as opposed to the IMEI as in non LTE phones. They also modified their 3G network to use SIM based authentication for 3G data as opposed to IMEI. If this is true it would prevent you from accessing the 3G CDMA based data network because the phone would be passing SIM based authentication for data and the network was expecting IMEI based authentication. In theory you could flash a different radio firmware if you can find it to correct this... but currently as Verizon is the only carrier of this phone I do not believe there are any alternative radio firmwares available. Community....please correct me if i am wrong but this is my understanding.
