Hello all, Bit of background. I bought an iPhone 4 in good condition apart from the fact that the device was dropped and the back panel cracked. Thankfully it didn't effect the screen in any way. Now the issue I have is that when I plug in headphones they don't go all the way until they kind of click. They just won't go on far enough. I can't apply any additional force as I don't wish to break anything and potentially ruin calling etc. Now I have looked and cannot see obvious blockages or anything that would physically stop something being plugged on, is it possible the fall caused something to move out of place? Is there anything I can do?
