Here's why I ask. I have a Verizon Galaxy Nexus, with a micro sim. I bought my iphone 5 at full retail so I won't loose my unlimited data. I'm hoping I can go to a verizon store on Wed or Thurs and ask them to activate and give me a new nano sim that I can put into the adapter that I already bought, use it in my Nexus, and then Friday put it in the iphone and not worry about having to go through a new activation process with Verizon.
