I accidentally upgraded to 4.2.7 not realizing it would F up my jailbreak. I have a lot of songs I loaded via Pwntunes I can no longer access plus some videos. Is there any way to roll it back? Something told me to not update the OS when I connected to my PC, but I thought it would be ok. I am now sick to my stomach..If I can't roll back, any ETA on the jailbreak?
