I live in Seattle and Sprint has supposedly flipped the 3CA switch. My understanding is that the S7E (among other compatible devices) should of received an update to enable the device for 3CA. Has anyone in a 3CA market seen increased speeds or received an update to their phones? I'm patiently waiting...
