Yes, you can use a Straight Talk SIM card in an AT&T iPhone, provided the phone is unlocked or compatible with Straight Talk's network. Straight Talk uses AT&T's network, so AT&T phones typically work well with their SIM cards. Just ensure that the iPhone is not locked to a specific carrier and that it supports the necessary bands for Straight Talk's service.
Yes, the Moto X in both carrier and unlocked form should work on Straight Talk. I would suggest that if you have a carrier-based Moto X now, you would pick a Straight Talk service that uses the same network (ex: AT&T to Straight Talk AT&T).
The Straight Talk service allows people to bring your own device. So, a Samsung Galaxy S3 should be compatible with Straight Talk, even if your phone was purchased through a carrier. For instance, if you purchased a phone through AT&T, and want to switch to Straight Talk, you can utilize the same AT&T network coverage if you pick a Straight Talk AT&T plan. Early termination fees may apply though if you choose to break off your contract to join Straight Talk.
Contact AT & T, and ask them for your Port Authorisation Code (PAC). Once they give you that, contact Straight-Talk and give them your PAC. They will then contact AT & T, to transfer your account.
