Oddly I've suddenly lost all sound on my iPhone, I upgraded to 1.1.4 (full restore) and got everything re-installed and all just fine, turned it off, and then turned it back on a few hours later, and no sound! I've tried rebooting, changing all sounds options, flipping the silent/ring switch like mad, still nothing :S

Any advice?

restsever options restore , do several hard resests, plug headphones in and out several times, or if you installed a app right before this happend uninstall it and do several hard resets

By hard reset you mean hold power+home button right?

I managed to make it rumble.. I spose it's a start, will start uninstalling stuff, thanks
