As what the title says, my uncle had restored my iPad 1 to someone in a mall using a third-party computer, and now I realized that my iPad is jailbroken because I saw my Cydia the day after he did it. Few days later, my Cydia and all my other system applications were missing (some only). Well, when I connected my iPad 1 to my PC, and investigated on my iPad, I saw Cydia and other system apps on my iFunBox! Please help me how to get these icons back, and do note that I don't have SBSettings or Poof used in this situation. Any help would be appreciated.

Thanks.
