Hello everyone,
After wanting one of these for 2 years, I am finally going to purchase one to toy around with. What should I check for in terms of whether the phone is defective, in bad shape, or broken? One thing I will check is if the GPS and A-GPS are functioning properly.

I am just a little worried as most of these are out of warranty and I'd prefer to make sure it's good within the first few days so that I can return it, rather than try to sell a broken device to someone else.

Also, does anyone know if the N9 supports line-out audio to an amp like the FiiO E7 via USB or the 3.5mm jack?
