I have a 1.1.3OTB 16GB, I just did the downgrade to 1.1.1 and *#307 jailbreak, and used i.unlock.no as the jailbreaker.

Haven't been able to test much but did notice that youtube works, however
no sound comes out of the speaker unless the headphones are plugged in, and then it doesn't come out of them, only the speaker.

Unless I pull it out half way and fiddle with it then it will come through the headphones. I think this is because the contacts aren't properly seated (similar to when you would pull headphones out anything half way and only get one ear)

When they are plugged in properly the sound only comes out of the speaker and is SUPER loud, even loud at low volume.

Is there some patch or way I can fix this???
