After reading here and ask about the latest JB I decided to proceed with my device's update. I have / had a 3G iPod Touch with OS 3.1.2 jailbroken with blackra1n. Here I leave the steps I used: 1 - I tried a restore (undo earlier JB) to the 3.1.2 without JB with Shift + Restore in iTunes(9.0.2). The answer was f***u, it gave me an error(I don't remember what). I coudn't choose the restore file because he didn't give me that oportunity. 2 - Then I tried to update to OS 4.0 and he asked for iTunes 9.2.1. I downloaded and installed it. 3 - With iTunes 9.2.1 I updated my device to OS 4.0 with no problems. All the apps were still there but without the chance to run them. 4 - In the iPod using Safari and accessing Jailbreakme.com I jailbroke my iPod gently and smoothly like a baby's ass. Read the last info about this jailbreak. Final result: I have all the original applications running well, I didn't lost any information (music+videos+apps), the jailbrake is now an untethered multitask one. Right now I'm analysing Cydia. I'll be back.Please Register or Log in to view images PS: Please note that my situation may be slightly different from others according to the type of facilities and applications on your computer (firewalls, firmwares ...I´m working with Vista). There's always a risk that I took too.

InfiniBoard doesn't run and I had to delete it to avoid the annoying "safe mode", now all my apps are gone.Please Register or Log in to view imagesPlease Register or Log in to view imagesmad:Please Register or Log in to view imagesPlease Register or Log in to view images Do you have any idea to restore them?
