Seeing as the Photon has quad band ability. Can/will it be able to roam on a GSM network in the USA? I currently have a EVO4G and there is a dead spot at my property in the country and my phone wont work very well at all. I even tried the verizon PRL and it was no better. A friend came out to my property and his phone on AT&T worked fine. If the Photon will roam on to AT&T's network, that would be awesome.
