Any LTE Qwerty Sliders for AT&T?

[zachavm]

I've got a moto x right now and love it, but my ideal phone is ALWAYS a qwerty slider. AT&T seems to have the worst selection of sliders across the carriers.

Does anyone know of any slider that works with AT&Ts LTE and HSPA+? I'm hoping to use it on AIO. I'll consider any unlocked option too. Is there a CDMA phone that has a GSM radio that would work? Any unlocked options? A T-Mobile phone with compatible frequencies? Anything!?!?!

Found this guy. If I can get it unlocked does anyone know if it will work on all AT&T LTE?

It will obviously work on their AWS, but the question is the 700MHz. The specs say "LTE 700 MHz Class 13", but AT&T is band 17. Both on 700MHz.
