I recently had to replace my iPhone and the worst part is my new one can't be jailbroken :-( The main thing I use my jailbroken iPhone for was tethering because the built-in tethering reports to my carrier which is bad I used a program called PDAnet. i also bought auxo which was my favorite tweak ever the Internet is not helping me basically all unable to find out isUDID registrations can allow you to pirate apps I don't care about that. but basically it's because it allows to run unsigned code correct? My question is can jailbreak tweaks and or other apps like PDAnet run on a iphone with a UDID registration? Presumably any app that needs root access wouldn't work but not all tweaks and that would use that. correct?
