I have a 3g iphone that has an intermittent speaker problem. sometimes it works, sometimes it don't. this isn't related to the famous headphone problem. because: if i slide a thin piece of hard plastic under the dock connector, the speaker will work. well after discovering this, i cut n trimmed a custom piece and put it in there. but after a while this trick stopped working i would have to wiggle it, then it would work for a while and stop. the problem is slowly getting worse and worse. it really sucks not having a ringer AND vibrate. i miss ALOT of calls and txts. sometimes if i put enough pressure on case itself it will work too, although there is a small crack allowing flex. i have had phone apart numerous times, most of which were to replace OTHER parts including camera module twice, headphone jack and twice on the infra red / proximity sensor after recieving a faulty one, adn then of course to check on this most recent problem. has anyone heard of this, or is my only option to replace that whole assembly? i cant see ANYWHERE a loose connection or break and don't even really understand why this is happening or why my work around is even possible. FEEDBACK, SUGGESTIONSN PLEASE!!
