I want to get a NES emulator on my iPhone, but I don’t want to lose all the apps I already have. My understanding is that jailbreaking would cause me to lose my apps, or at least prevent me from getting new ones from the iTunes store. Any idea how to do this and not only keep what I have now but also be able to get more apps from the store in the future? How do I get NES emulator on my iPhone without losing apps? I would really appreciate your useful information pertaining to my query. Thanks.
