This suddenly happened that when I make or receive calls I can't hear anything, but it seems phone connections are fine. Then I enable the speaker, the phone call is smooth just like normal. Is this most likely a software or hardware problem? What can I do about it.
I am currently on iphone 4 iOS 5.0.1 jailbroken.
