I'm currently running non-jail broken firmware 2.0.2 im in the process of jail breaking my iPhone 3G at the moment. When a new firmware update is released from apple and I update will my iPhone be bricked and non-functional due to the fact I jail broken to phone or that doesn't apply for jail broken phones only if it is unlocked. Once I do an update on 2.0.2 jail broken iPhone it will be reseted to factory defaults therefore it has to be jail broken again on newest firmware? Can anyone confirm this?
