As the title says I am upgrading from iOS 3.1.2 (jailbroken with Blackra1n) to 4.0.1. I will do a restore to 3.1.2 first however, and then install a custom 4.0.1 Sn0wbreeze image.
There are a few apps that I'd like to save date for however, e.g. games, navigation tools etc. Does anyone know where I can find the app data for backup, and then where to restore it in the new iOS? Not sure if the file structure is the same.
