Nokia USA will NOT support the warranty. You can send it back to the country of origin and incur the shipping fees which would probably be offset by a) buying for a good price and b) having a local repair center fix. While not as flimsy as the N900, the USB port isn't super-strong, so make sure the USB fit is still snug. Like many Nokia phones, they are particular about chargers and cables. See that it comes with the original charger and cable if possible (You will probably need a plug adapter). It's an interesting screen to see. Sometimes I like using the phone late at night and I like how it isn't so bright like my old HTC Sensation/Amaze and current Lumia 900. Those phones are too bright. On a pure white background in the darkness you will see the peculiarities of how the N9 shows pure white. Blacks are inky, pure white is more off-white. Check for flaking finish. Check if it's got a "Creaky case" in case that's a big deal to you (makes a noise when pressing volume or power buttons). Why buy used when you can get brand new ones for just a bit more on places like Amazon? Good luck and enjoy, it's an beautiful experience, especially the low-power standby screen. I'm transitioning to a Lumia 900 (hiss) but enjoyed using my N9. Where are you located? I live in the US and you could see mine if you're local.
