If I already have a version of an app, on an older jailbreak where I've used FLEX to locate certain boolean named classes and var classes (as in, I know the names of the classes I want to modify) and had this working the way I wanted it to work, and now I'm looking to either modify a current version of the app and sideload in a modified tweak (I have a developer account) on either a non-jailbroken device, or a more current jailbroken device. What tools might make this the easiest? I've got coding experience in other areas, but iOS I have not dabbled in too much so it's rather confusing.
