So I jailbroke my iPhone 1.1.4 using the new ZiPhone thing.

And my phone is synced to a bluetooth device (my car)
and each time ive tried to do this (ive tried several times to see),
it completely messes up the phone part, makes it so i cant hear
anyone and makes voicemails be blank even though they arent...then when i restore it the voicemails are there.

it basically messes up the entire listening area...speaker/not speaker and then my bluetooth device/iphone/speaker. none of those buttons do what theyre supposed to. I think it starts when i put BSD subsystem on? I'm not sure

can someone help?
