Is it possible that having my iPhone jailbroken with: -iNav Theme -SBSettings -Backgrounder -LockCalendar Causes the iPhone to have too little memory for my bluetooth headset? (Plantronics 925), causing people to barely hear/understand what I say. I have tried with Full 3G and Edge signals and they say the voice goes in and out. I know its not the bluetooth because have tried it with other phones and its great. Any thoughts?
