If your talking about doing the SIM free through the iPhone upgrade program then lets say for my example. I have straight talk right now currently with my iPhone 5s. I take it in and take out my current SIM card, activate the phone, insert the card into the new phone and BAM. Activated in store.if it is a Sim free phone, how do they activate it in store? Based on the front page article it doesnt even come with a sim. I wouldnt think they would have many carrier sims in store. I'm not seeing how it would work with the AUP requirements
