Hello all, complete noob here. I'm getting a new-in-box N9 tomorrow. Very excited. I def want to update the phone. If I do it first thing after unboxing I shouldn't have any problems correct? Is there any upside to downloading via OTA vs. USB with the NSU? Should I do a hard reset after the update? Thanks in advance, I'm already learning so much here and I don't even have the handset yet!
