I have a jailbroken 2G iPhone and just got a 3G that is jailbroken. I will use the 3G on a normal basis but I may want to use my 2G in situations where it may get beat up some or there is a higher chance of me losing it (plane trips and hotels). Will all my Cydia apps and settings sync up the same as my most current 3G sync with iTunes when I connect it, or will I have to redownload the apps within Cydia on the 2G to keep it up to date?
