My confusion with SHSH and "Older" versions
OK, first things first, I'm on a totally normal working 4.1 Jailbreak on my iPod touch 4G. I ONLY have the SHSH blobs from 4.2.1 saved because I got it for christmas so missed the older SHSH window...
I do however have some firmware from my old iPod however, including my iOS 4.2b3 firmware which as far as I'm aware is necessity to jailbreaking your iPod touch at 4.2.1.
My questions are:
1. Where do the SHSH blobs come from, the device or apple?
2. If I were to restore to iOS 4.2b3 on my iPod, for starters could I do so now, and if I can, would I be able to save SHSH blobs for it now?
Thanks in advance,
