No problem: note I'm speaking strictly as a user of AT&T and their devices. I would tell you to get the HTC One M8 w/ WP8.1, but it's clear from these forums that even that device is not without issues and has a notorious reboot causing bug that HTC refuses to acknowledge.
Speaking of waiting on new AT&T phones, all I see announced for windows is the Lumia 830 which to me seems like a step back from the already on the market 1520, 1020, 930/icons.
Ugh.... AT&T is like the ex-girlfriend you keep getting back with, but on the 6th or 7th time you're like "OK I'M COMPLETELY DONE WITH THIS". Yet here I am... FML.
