Hi, I have bought a iPad recently in a private store and get jailbreak. The store keeper has also downloaded some apps into my iPad. After I come back to home, I try to transferred some new apps into the same iPad with my PC, and unfortunately, the synchronizing process is in fact deleting all my pre-installed apps inside !!!!! I immediately pull off the cable. Now, whenever I connect my iPad with my PC, the synchronizing process will then start and erase all the apps. How can I solve that? Please advise. (I rarely use iTunes and maybe that's why I don't know how to overcome it). Thank you.
