Rumors have been flying for a couple of months that Verizon is set to introduce LTE phones with world roaming capabilities any time now. But according to the practical experimentation of one XDA Developers member, the HTC Rezound already has this ability, somewhat hidden. When "i rule 123" disabled the 4G LTE radio on his Resound, he noticed a new option for a Global mode. He popped in a T-Mobile UK SIM card, and lo and behold, it both made and received calls - no hacking required.
