3GS Backup before Factory unlock questions
Hello everyone. I'm new here. I have a few questions for a noob. I have a 3GS that has been Jailbroken (with 4.2 iOS, I believe). It has not been synced (sunk? ;) ) with iTunes since the Jailbreak, and it's been a very long time. I've loaded everything myself. I'm living in Germany. The way that the German system works is that after 2 years, your provider MUST unlock your phone, even if it has been jailbroken. SO, it is now time to do that.
Now my questions is this: is there a way to back up EVERYTHING on my phone (contacts, sms, notes, program data, like I said...EVERYTHING) so that after it has been unlocked, I can again, use all of that data without too much hassle and time? And yes, I am aware that my Cydia apps will not work any longer. Can ifunbox manage this? I'm not sure what to do, or even if it's totally possible.
Thanks for all of your help! You guys ROCK!
