Ok so i shattered the display on my iPhone 4... got a replacement from apple for the $199 deal. From what I understand the SHSH blobs are device specific correct? So even though I "made my life easier" it's not possible to downgrade to 4.0.1 via Tinyumbrella to my old blobs since the entire device in new. Stuck till the new JB is released for 4.1. right? Just making sure I understand this correctly. Thanks for your help guys!
