crashnburn_in Posted April 3, 2010 Share Posted April 3, 2010 Help! FW Update : iTunes & FW Version Issues? This chart shows the Release Sequence with dates and version numbers for iTunes and iPhone Firmwares: Picasa Web Albums - Abhi Typical Update Process involves the following steps- • SyncBackup of iPhone FW A by iTunes X • JB/Unlock by some Tool • Restore FW B by iTunes X • SyncRestore iPhone FW B by iTunes X Now here there is a huge gap between what I currently have & where I need to go. iTunes: 8.2 iPhone 2G: 2.2 Now, I know 8.2 can handle Backups for 2.2. My fear is there might be some issues / incompatibility between iTunes versions / iPhone FW that are too far apart. Now, I am wondering if it might mess up my • iPhone • Backups • Cracked IPAs • Cydia Apps • Any other Settings / Data I am wondering which of the following is what I need to do: 1) I update to iTunes 9.0.3 / 9.1 assuming and hoping it safely works with 2G 2.2 (I am wondering if that would be with / without cracked apps). Anyone experimented with that? • Update iTunes X > Y • SyncBackup of iPhone FW A by iTunes Y • JB/Unlock by some Tool • Restore FW B by iTunes Y • Sync Restore iPhone FW B by iTunes Y 2) I update to iTunes 9.0.3 / 9.1 in the middle assuming & hoping it does no mess the SyncBackups & SyncRestore Data i.e. SyncDATA is handled / managed across versions (I am wondering if that would be with / without cracked apps) • SyncBackup of iPhone FW A by iTunes X • JB/Unlock by some Tool • Update iTunes X > Y • Restore FW B by iTunes Y • Sync Restore iPhone FW B by iTunes Y OR 3) Do I need to do some R&D to determine which special sequence involving multiple versions of iTunes works best? Especially given the order of / releases and Release dates of iPhone FW & iTunes. ALSO: Cracked Apps / .IPAs that are in iTunes & on iPhone… How do I ensure they survive when I go across from a: 2.2 FW: Mobile Substrate (Some pre-AppSync that allowed Cracke IPAs) to 3.1.x FW: AppSync for Installd Link to comment Share on other sites More sharing options...
