I just got into the world of jailbreaking yesterday and jailbroke my iPhone 4. I am going to JB my girlfriend's 3Gs this week. I was wondering if, like regular apps in the app store, can jailbreak apps be shared between our phones, or would I/we have to download and/or purchase each app twice so we could each have them? I tried a search and couldn't find an answer to this.
Also, if I have jailbreak apps and sync with iTunes, will iTunes delete the non-app store apps? What about if there are any updates to iTunes or anything? Would I be at risk of losing them then?
So when I sync to iTunes, any cracked apps will sync like normal, but any jailbreak-exclusive apps will do what? Will they be ignored by iTunes as if they don't exist on the device and they will only remain installed on the device?
My appologies. As you can see by my post count, I'm new here. At least to the jailbreaking parts of the forums. I was just merely trying to make sure I understood the differences in the types of apps and how they sync or don't sync. I don't have any or condone using pirated content.
