Well, the Motorola Droid 5 possibly for Verizon has leaked. In recent, those new Verizon Moto LTE Devices have been able to run on AT&T and T-Mobile's HSPA Networks. Not 4GLTE, but I'll take it. Now for those who aren't up to speed, don't mock me, yes Verizon uses CDMA, but they use GSM for LTE, hence the sim card slots on their devices.
It's supposed to be rugged and have built in Qi-Charging!!!!
Not to burst your bubble, but nobody was able to successfully unlock the Droid 4 for use on USA GSM Networks.
The Droid 3 circa 2011 was the last Verizon phone that was brought onto USA GSM networks, so I wouldn't get your hopes up.
