Ok, So I have my iPad jailbroken on os 3 now if I go to 4.2 beta do I need to do anything special because I have the swap file hack installed. Or is it just going to get rid of it once I go to 4.2 beta? Just wondering if I have to manually turn off the hack before going to 4.2 beta basically. I do notice with the iPhone like if you do MMI it keeps even after you un-jailbreak it.
