iPod touch 4the Gen headphone jack problem. PLEASE HELP

It sounds like there is something stuck in the bottom of the headphone jack( normal problem). Have you tried cleaning it with Compressed Air??

I have just encountered the same problem with 2 iPod Touch 4g (8gig) devices. Totally unexpected, since my older iPod Touch 2g has never had such a problem. One moment the headphone 3.5mm stereo mini-pin inserted all the way, and the next it hit a barricade.

I'm seeing headphone jacks going for less than $10. The range of difficulty, however, is high, so I'm comtemplating whether to try it myself or to send the iPods out to one of the many iPod repair services. If a hot device is required to loosen the adhesive before attempting to pry the iPod open, I'm already discouraged from trying it myself.

If I get the iPods back to accepting an earphone jack, I plan to look for a cover that does not leave the headphone port exposed.

Compressed air worked for mine. Had a piece of lint stuck in there

You could also try a small dental pick. The issue is that the blockage is usually a mixture of paper and pocket lint that has been compressed at the bottom by yor headphone plug. Gently move the pick around to break up the blockage and then retry the compressed air.

Good luck and remember, be gentle.

I would make an appointment at the Genius Bar of an Apple store. Before then, be careful not to further damage the jack, they will void the warranty on the whole iPod.

I just used a staple here at my desk to do it. It worked great, no compressed air at all. Just scraped it out.

Again, Very Gently.
