Can jailbreak apps be shared between 2 iPhones on same iTunes account?
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?
