Headphone connection sporadic and must twist to get good connection; is there connection problems with connection port?

Question

More times than not the headphone i purchased from Apple Store (Nike) and others do not get good connection in port of the nano so cannot play; if i twist it in the port it might hit and get sound but then can loose it with movement and/or get static; any history/problems with ports allowing good connections with headphones; it is surely fully pushed in; thanks

Thanks for the quick reply.  The use of a heat gun to loosen the adhesive complicates matters, but your point about the 4G's unsoldered jack brings it back into the realm of a possible self-fix.  I've read the notes by other users--some were successful with pipe cleaners or pressurized spray cans or both.  I'll try that first before going for disassembly.
The first repair place that comes up when I Google "iPod repair" prominently features headphone jacks for the iPod Touch, suggesting it's a pretty popular item.  Maybe the placement of the port, or even its angle, is a receptacle asking for trouble.  If I get it to work again, I'm going to look for a leather, or folio, type of covering that doesn't leave that hole exposed.
