    Hello All,
    I have iphone 4 and it was locked on at&t and was running ios 5.0.1, now i have unlocked my iphone and now i am using ios 5.1.1. But i have a problem, when i call someone i cant hear anything "no dial tone sound and no sound during call" & speaker mode is also not working and nor the person cant hear my voice. I also tested on my another phone but same problem.....

    So can you tell me is this a hardware problem or software problem ?? and yeah i can record voice memos and i can listen my memos with speaker on and off :confused:

    Waiting for reply....
