Just picked up a Pre 3 (AT&T), swapped the sim out of my my Pre+. After it booted, everything seemed good, but I wanted to switch back because I had yet to modify my touchstones & my case hadn't arrived yet. That's when things went wrong. When I put my sim back in my Pre+, it seemed mad that I was still signed in my profile in a different phone, did a reset & wiped a bunch of info that assumed I could keep on my old phone.
I'm sure its too late to fix that problem, but in the future should I sign out of my profile before installing the sim in the other phone? How is that even done?
I'm afraid to put it back in my Pre 3 without logging out in my Pre+, but I want to play with my new phone
