I'm selling my wife's iPhone and the person might be interested in keeping the current firmware (4.3.2) for JB reasons. If I "Erase All Content and Settings", will the new owner have to upgrade to 5.0.1 firmware when they get it (since this phone is new to them and their computer, thus they won't have a previous Restore on their computer)? My gut says, "No", that the firmware stays on the iPhone even after an EACaS. Please let me know a.s.a.p. as I want to ship this out to the buyer today. Thanks, J.
