I still do not agree with epoxy as a remedy as you STILL have to take the device apart to do even that so why not do the simple soldering job needed for a preventative fix?.

A thought for you here ok.... the jacket may well stay soldered but what if the plastic inside of the jacket breaks up or you need to replace the port itself for any reason? this expoxy your on about is not possible in that small area to hold indef and to get it off will be a nightmare of a situation.
