A Weird issue in iphone 4

Hello all,


This problem is discussed in many forums and in many threads in this forum. But I have a very different situation. I purchased a iphone 4 locked to AT&T. I unlocked it using gevey sim and then jailbreak it using jailbreakme.com. It was running 4.3.3 and BB 04.10.01.

After all this I tried to call someone and found out that ear piece is not working. I searched it on different forums and some people suggested that a clean restore can fix this. So I updated my phone to 4.3.5. and to bypass the activation screen, i again jailbreak it using redsnow, though its tethered. unlock works perfect even better than 4.3.3, jailbreak, installous, cydia everything is working fine but still ear piece is not working.

I checked it using voice memo, recorded some voice played it on speaker, I hear the voice but when I tap the speaker button to direct it to another speaker, nothing happens, i mean i cant hear anything.

I checked ear phone port for any dirt, inserted and pulled out the ear phone's pin a few times, applied every proposed solution available on web but in vain.


Any body please suggest something. Or Do i need to replace the ear peice?

TIA

 

Yeah, I am thinking to do so. But I read somewhere that ear piece stops working after jail breaking. Has any incident happened like this before?

 

I purchased it from US and I am far far away from US and there is no apple store in my country. Lets see what happens. Anyway thanks for the suggestion.
