As I posted in the trivial thread,
today my iPhone 4s has decided that it has headphones plugged in despite there not being any.
This means it refuses to make noise out of the speaker, if I plug headphones in then it's fine.
I've reset it, turned it off and on again, cleared out the audio jack and now restored it via iTunes and it's still happening!
Anyone here had this and any ideas?
Was bought on release day so just over a year old.
Cheers all.
most likely some dirt or something stuck in the headphone jack. can you get your hands on some compressed air?
