Sound not working after jailbreak 4.2.1
I jailbroke my iphone 3g 4.2.1 using redsn0w_win_0.9.6rc16, and unlocked it using ultrasn0w 1.2. I used pwnage tool beforehand to switch my baseband to 06.15.00.
For some reason, I lost my sound. I tried plugging in, still didn't work. I can receive/make calls, but I can't hear their voices, nor they can hear mine.
I re-jailbroke it like 3 times, and on 3rd time, sound actually worked. Then after a while, my iphone froze on me, then after I rebooted, sound was gone again.
I feel hopeless, I couldn't find anything on google. Friend tells me my sound drivers are probably corrupt, perhaps it's a bad ipsw file?
Your sequence of actions don't make sense.
Pwnagetool creates a pre-jailbroken IPSW that you restore onto the phone. After this you would NOT need to use redsn0w.
That version of redsn0w is probably too new to work properly against iOS 4.2.1 - what IPSW did you supply redsn0w with when it asked for an IPSW?
It could be a hardware issue. I can't recall seeing anyone else report this issue in the past.

Mine has done the same and I can't get the sound back, any ideas? Please reply. I can use it as speaker phone or blutooth only. iPhone 3G back says 16GB but Mdole is MB702LL Yahoo serch came up with 8GB. 4.2.1 (8C148) 06.15.00. Don't know which redsn0w or unlock was used, bought it Jailbroken/Unlocked. Said sound worked before jailbreak now it doesn't.
get the DUST OFF can or any spray air and spray in the headphone port. there is a sensor in there that stops audio to external speakers when it get covered. this is how the iphone knows the headphones are plugged in.
