AppSync has been updated so that it can be used with the new
iOS 4.1 firmware. For those of you who don’t know,
AppSync patches MobileInstallation file on iOS which is needed in order to install .ipa files manually without using
iTunes.
Keeping the current
Jailbreaking scenario in mind, official tools for jailbreaking new iOS based devices on firmware iOS 4.1 aren’t available yet, but we have reports that the Jailbreak will be
out soon for iPhone 4 running iOS 4.1, the new iPod touch 4G and the iPad. The devices which are jailbreakable at the moment running on iOS 4.1 are the
iPod touch 2G (non MC model),
iPhone 3GS (old bootrom) and the
iPhone 3G. But when the jailbreak for iOS 4.1 is out for all devices, this guide will be applicable to other devices too.
Before you carry on with the installation of AppSync 4.1, make sure you have a jailbroken iPhone/iPod touch. Instructions for jailbreaking iPhone 3GS (old bootrom) running iOS 4.1 can be found
here, for the iPod touch 2G (non MC model) can be found
