Using another cable/plug to charge the S4
In one of the instruction manuals that comes with the SGS4, it says to only use the USB cable and plug that comes with the phone. I dismissed that (mostly b/c I don't like the white cable/plug when I have a black phone) and am using generic micro USB cables and the OEM plug that came w/ my Droid 3. Am I doing any long-term harm? It seems to charge just fine, both via computer and wall outlet.
