My Nexus 4 made the jump from StraightTalk to Aio wireless a few days ago and is doing quite well. I am out of one of the launch cities of Aio and am getting really great service data and voice. I am averaging 7mbps speeds consistently on HSPA+ network and have had no problems.
I also wanted to post the APN settings for those looking around for this is a relatively new service and the APN is not yet listed with any app I could find. Note the MMS takes up to an hour to get established on your line for some reason but it is working for me.
