Hello. I got an iPhone 4G I bought like a month ago from the US. it came with iOS 4.1 and it's jailbroken but not unlocked. My question is that my Mac OS is a bit laggy and i'm interested to format it and to install a Fresh Mac OS, Now i saved SHSH on my Tinyumberlla when i got my iPhone 4 and i believe i might need it for later, Is it possible to back up my SHSH Save on my TinyUmberlla so i will be able to use in it after the format on the new Mac OS? Thank you so much for the helpers!
