I had my phone charging at my desk when I suddenly noticed a high pitched whine/chirping coming from somewhere. I was quickly able to pinpoint it -- it's my charger. I did a Google search and it seems to be a fairly common issue with AC wall chargers. I'm just curious, is this something I should be concerned about? While it's annoying, I can certainly put up with it until I can have Verizon replace it but I don't want to have to stress about some electrical surge nuking my phone. Thanks for any and all input! EDIT: Oh, just now the charging finished and as soon as it did (mind you it's still plugged in) the noise ceased.
