https://fjallfoss.fcc.gov/prod/oet/f...ive_or_pdf=pdf That's interesting although that's contradictory to my experiences. I used to buy a lot of devices abroad whenever I'd travel. It was a bit of a crapshoot because if the phone ever died, I was pretty much screwed. Heck, once I even had a minor software issue and when I called NokiaUSA support, they were reluctant in helping me out because my device wasn't bought in the US. Don't even ask me about trying to get replacements - I was pretty much on my own. I never did bother registering my devices so maybe that's the key? Somewhat strange because for other NAM devices I've bought, I could get them exchanged or repaired without having to register. If for whatever reason I have to purchase devices from abroad again, I may have to give that method a shot.
