hello. i am about to restore my jb ip4 to 4.0.1. it has always been at 4.0.1. reason for restore is to hopefully fix a sporadic reception problem. last resort is to return unit to apple store. i've read the forums/blogs on restoring via saurik. my shsh is saved/restorable and i have saved the correct 4.0.1 firmware. i think i am set. main question: does anyone know if itunes 10 will cause any problems with the restore? i really want to avoid itunes 10 "accidentally" upgrading to 4.1. i know itunes 9.2.1 works and an option is to downgrade, but i want to avoid this step as well. any thoughts?
