Hey so ive searched all over for this, i dont think this has been asked before. so i noticed today that there is a little bit of rust on the dock charger (not mini usb) of my 8820. i dont know what to do about it but i did just try a little CLR (i know probably a stupid idea). but is there anyone out there that has had this problem before? Also let me be clear that i have not droped it in any water or gotten it near any liquid. i dont think its sweat eather because my hand is not really near there when typing. Thanks again guys for any help and advice!
