Just go tomycricket.com, and enter your zipcode to find compatible phones. Even look on phonescoop.com, and check the specs. of every phone. Make sure when you look on phonescoop, that you look for the 1700 band in the specs.
BTW, I included the link to go to the actual Cricket portion of phonescoop, so you have easier access to the actual part of the site. Also, Chicago, Milwaukee, & Madison Wisconsin are AWS only markets.
