When it comes to updating and/or installing the iOS, does it matter if it's done over Wi-Fi or thru iTunes?  Is one recommended over the other?  I have used both ways over the past few years and so far have never encountered any problems.  I do back up before each upgrade or patch.  Just wondering if one way is better or more stable than the other.
