Hey guys...this might be a stupid question, but I'll ask anyway. I really miss the size of the 5S, and I've decided to go back. So, I'm dumping my 6 and upgrading back to a 5S...yes, I said upgrade. The bigger size thing is an illusion as an advantage...however, I'm curious...if I buy a 5S used for example, can I simply take the SIM out of my 6 and stick it in my 5S and it'll be rocking or nah????
