HTC's latest supersized handset might be making its way to the land of the supersized meal, if this recent FCC listing is any indication. The documents show a HTC handset that bears the model number OP3P500, a slight variation of the international One Max's OP3P510 model number which you can see here. Further, the OP3P500 appears to support LTE band 17, a clear sign that the phone is compatible with AT&T and could be making its way stateside some time soon. Of course, no pricing or availability information can be gleaned from the filing, but you can check out our full review of the One Max before you decide if you want such a giant phone in your life. At least it's smaller than the Samsung Galaxy Note 8.0, right?
