I have an iPhone4, was JB 4.3.2.
JB'd with PwnageTool 4.3.3.1 up to 4.3.3
restored from iTunes and from PKGBackup
Everything is great, BUT no sound from earpiece (at all) but full sound from speaker.
Can't hear anything on phone calls unless I switch to speaker.

Everything else works.
Did re-JB with redsn0w 0.9.6r16
Rebooted several times. Reset (power + home) several times.
Still now sound.
Tried plugging and unplugging headphones
Still no sound.

Ideas?
Thanks
