since updating to 5.0.1 today with redsn0w and downloading ultrasn0w through cydia my loudspeaker/speakerphone won't work properly.

I can hear them but they can't hear me, if i switch speaker phone off they can hear me again, but if i put speaker phone back on again they can't hear what i'm saying.

wondering if this is common problem or if there's a fix (fingers crossed).

also let me know if you think this would go better in another forum...
