Months ago I wanted to download some apps without having to pay for them, so my friend jailbroke my iPad for me (which was in v3.2.2). he didn't get to explain how he did it or how jailbreaking works so am a complete fool about it. I found out there is the new version right now so I was wondering if I can update my iPad to 4.2? or will that erase the jailbreak or make my downloaded hacked apps unusable? would appreciate any help thanks in advance.
