Fix iPhone No Sound Error

This is a fix for iPhones running iOS 3, 4 and 5 that have the 'no sound' issues. Usually the sound only can be heard when applying headphone. Here are the solution to fix the error:

1) First you must make sure your iDevice jailbroken.

2) Download and install 'iExplorer'. It's available for both Mac and PC


3) Connect iPhone to your PC/Mac and run iExplorer

NOTE: if iExplorer won't work for you, download 'iFile' through Cydia and you can perform the following steps to this fix directly on the iPhone!

4) Within iExplorer (or iFile), on the left column navigate to System / Library / LaunchDaemons

5) Within the right column find 'com.apple.iapd.plist', right click then select delete

6) Close iExplorer and reboot the iPhone....YOU MUST REBOOT!

7) Enjoy sounds again on your iPhone!

NOTE: Deleting the 'com.apple.iapd.plist' may effect the functioning of hardware accessories that go with various apps, such as FM transmitters and Nike accessories, etc
