A quick question about downgrading.
I'm in the market for a used Iphone 4 or Iphone 4S.
Unfortunately most of the units I'm find on Craigslist, the owners have updated to IOS6.
Not only do I not like IOS6, I need a jailbreakable and unlockable OS so I can reload my apps & tweaks and use it on Tmobile, which means IOS5 or below.
- Can you use another individual's blobs? i.e. Can someone who saved their blobs on their computer via TinyUmbrella or another method, email them to you for use?
- Is it absolutely impossible to downgrade a phone without the blobs? Even if you cook up your own custom firmware in Redsnow?
- I have Blobs saved for my 3GS up through 5.1.1.. Can these be used?
