If this is already posted please link me. Im preparing to update to 4.1 but i dont want to lose all my Cydia additions. If so how do i back those up so i dont have to redownload and reinstall them?
Rock had a great backup system, couldnt find a Cydia backup. I had to load manually after 4.1 JB. I took screen shots of all of the sources and packages that I had loaded for a quick reference.
Install aptbackup from the cydia store (it's free) and follow the directions in the program. It's real simple. I used it yesterday before upgrading from 4.0.1 to 4.1 on my iPhone 4.
AptBackup can be problematic. Apparently, PkgBackup is more reliable, but is also at a cost. This is just from me reading forums, and not an opinion I have formed through usage of both.
