OK first off you are going to love me and hate me. Here is your solution.
1. Put phone in DFU mode and re restore it to the custom ispw. Sorry that's the hate me part.
2. When done restore to back up. This will get you all of your contacts ect.
3. When that is done hopefully you have made it back from church safe and sound. #2 takes time. You will think your computer rebooted or something because you will be back at the same screen that gave you the choice of restoring from back up or setting up a new phone. Pick set up new phone. Don't worry this will only take a few minutes. When done you will have e-mail and all of your contacts ect.
