don't do this on a 1.1.4 phone -- it crashes like other apps that apparantly need/check for 1.1.3. i had to reset network connections.

up to date way of upgrading iphone (to make it easy for everybody): use itunes to upgrade, just like an unlocked iphone, to 1.1.3 then quit itunes start ziphone 2.4 unlock iphone (after that the iphone works fully) restart iphone and use ziphone 2.4 advanced options to downgrade/upgrade bootloader/baseband from BL4.6/BB04.02.13_G to BL3.9/BB04.03.13_G restart iphone and your on an iphone that works just like an unlocked iphone + it's jailbroken and has the installer.app on it... then take it from there... no media or settings are erased in that process, unlike previous upgrades that deleted all media and settings from the iphone... i tend to giving the advice to delete all 3rd part apps before doing this upgrade in order to make sure no old settings of those 3rd party apps are corrupted... just to make sure and it doesn't take that long to reinstall the 3rd party apps, the settings are not deleted by uninstalling the apps...

and why would you want to restore 1.1.1 in the 1st place??? doesn't make sense... stick to 1.1.3 !!! use ziphone 2.4 and read the read me files if you don't know how to use it...!!! reading helps, and don;t just apply stuff to your iphone if you don;t understand the underlying processes...

restore to 1.1.3, then use ziphone 2.4 to unlock. after unlocking downgrade the 4.6 bootloader to 3.9 and in the same instant ziphone upgrade the baseband to 04.03.13_G... 1.1.3 is the version t o use now! don;t mess with 1.1.1 or 1.1.2... ziphone 2.4 is for 1.1.3, and if your on bootloader 3.9 there's no need to change that... if your on bootloader 4.6 baseband 04.03.13_G can't run and your cell part of the iphone will stay silent... only BL 3.9 and BB 04.03.13_G work! BL 4.6 needs BB 04.02.13_G to work porperly... the downgrade (BL) and upgrade (BB) are to be found in the advanced option in ziphone 2.4... but first use itunes to upgrade to 1.1.3, then unlock, quit itunes, restart iphone. after that downgrade/upgrade BL/UL... if your on 1.1.1 you can't use 04.03.13_G @ all! only in 1.1.3 after applying all the ziphone features!
