Sorry if this has been covered before...tried searching but couldn't really find an answer. I have an 1.1.1 phone unlocked with iphonesimfree in November. I want to upgrade to 1.1.4...can that be done with Ziphone? Is Ziphone better or iPlus?
You'll need to check that the Ziphone software that you have is suitable for a 1.1.4 iPhone. Then connect to iTunes, do a restore and update to 1.1.4, then run Ziphone to unlock/jailbreak your phone.
If you have an apps installed using Installer, then you will have to re-install them afterwards, as the backup that iTunes does, does not include these apps.
