Has anyone who has used it successfully then tried to upgrade to 4.2? Does the jailbreak still work if you upgrade the os after jailbreaking, or do you then need a separate 4.2 jb after the fact? I'm new at this...
My earnest recommendation is for nobody to try that.
This is exactly why I seem to have trashed my iPad.
I successfully moved from iOS 4.2 back to 3.2, installed limera1n, and then tried to move back to 4.2 using the procedures that were successful before, and the device appears to be irrepairably stuck in DFU.
I have not been able to find any way out so far.
Maybe some smart person will help us out.
As I said in another post, no combination of attempts to re-set or hard start, no combination of the usual DFU re-set applications (RecBoot, blackra1n, Umbrella) will work.
So far.
