In a heartbeat for the 520 w att or its older brother the 521. its a dual core device w windows 8, only thing missing will be screen size (the lower pixels resolution looks good on small screen) and camera flash. I really don't care for front cameras.
Same here, came in a box and the associate opened it and tested it. Added it my line while 920 is off for 2nd repair in two weeks, starting to like the 520 alot, especially w sd card 😃
