Desperately in need of help downgrading 1.1.3 to 1.1.2
All of the guides I have read that cover downgrading from a jailbroken 1.1.3 (via Nate True's jailbreak) to a jailbroken 1.1.2 either give the instructions on how to do so via a Windows PC (I am on a Macintosh), or they describe doing so for phones with bootloaders 4.6 and up (1.1.2 Out of Box and later)...mine is bootloader 3.9 (I believe)
As I said, I am using a Macintosh, have the latest version of iTunes installed, have a jailbroken 1.1.3 iPhone (via Nate True's jailbreak), my modem's firmware is 04.01.13_G, and the first couple digits of the serial number of my iPhone are 7T725xxxxxx (which I believe means it was one of the iPhones from the first batch that shipped - week 25)
Jailbreaking my iPhone with 1.1.3, and then subsequently trying to fix the Google 'Locate Me' feature of the Maps.app with a lockdownd file that was most likely the wrong file has really screwed up my phone (no wifi, etc, etc.), and at this point I desperately need to know what the absolute simplest way possible is to downgrade my iPhone to a jailbroken 1.1.2 firmware, so that i can then apply the newer iphone dev team release of the 1.1.3 jailbreak)...
As noted here, in comparing the iPhone Dev Team's 1.1.3 release VS. Nate True's 1.1.3 release:
PLEASE HELP!!! I need to know the simplest, Macintosh/jailbroken 1.1.3 iPhone/bootloader 3.9 compatible method to get back to jailbroken 1.1.2 (to then apply the newer iPhone Dev Team 1.1.3 jailbreak)!!
Supposedly NateTrue's method will break functionality needed to support official 3rd party apps when they come out in February, so it is a good idea to use this method instead.
Any suggestions would be greatly appreciated... Thanks so much!
