Curious. If you are using your phone naked what do you do to avoid lint or overall gunk getting into the charger post? I have an Agent 18 I use sometimes but even that has the opening and I have found I will sometimes end up with a little lint or dust in the port. I am sure some covers, well cover it. But do they make a plug you could add? I find sometime if something in there I give a quick blow and it pops out. But I worry a little blow could include some spit (not trying to be nasty but you know what I mean) then adding to the charge could short out the unit.
