I'll try to make a long story short. I will be going from iPhone 4 to 3rd gen iPod Touch. My wife is going from iPhone 3GS to iPhone 4. And our friend is going from iPhone 2G to iPhone 3GS. Soooo... I want to transfer all data from 2G to 3GS. 3GS to 4. And 4 to iPod Touch. 2G - 3.0.1 - JB 3GS - 4.0 - JB 4 - 4.0.1 - JB I still want them all JB. And if I can have them on 4.0.1, that'll be great. Except the 2G of course. I'm assuming that one will have to be 3.1 or something. I have read up on how to back up JB data with Tiny Umbrella and AptBackUp. But I'm still not sure how to go about these transfers. Naturally, I want all contacts and the usual iPhone stuff transferred, but I also want the JB stuff. Any and all help will be greatly appreciated.
