    Hi
    I started experiencing this problem 2 days ago with iPhone 3g running 3.2.1- I was making a call and it was just mute (no error, reception was excellent). Then I tried to restart it witch crashed it completely.
    So I used Pwnage tool to install 4.1 soft on the phone and later jailbraked it with redsn0w. But it still has some issues... at some point it refuses to make calls (mute, no error) and when I try to mess with the settings it shows "no signal" and the signal never comes back. Now the wierd part is that the reboot always fixes it and it works good, 3g and everything and then randomly just won't make a call again while SMS works.

    Any ideas? Is there somekind of fix for that or should I try installing the 4.1 soft again?
    Thanks

    It might be a hardware issue with your phone or your sim card maybe.

    Next time this happens, try resetting your network settings to see if it starts working again.
