I know there have been question on this in the past, but none are not what I want. I haven't used my iPhone 3G ever since about June when I ripped the LCD ribbons. Monday I finally ordered a new LCD, changed it and everything went ok. Now my phone is on 3.1.3 jailbroken. When I used TinyUmbrella last night it said I had SHSH files on file for 3.1.3, 4.0, 4.0.1, 4.0.2 and 4.1. How is this possible when I never saved any blobs before? Since it says it has blobs for 3.1.3 I plan on restoring to it. My main reason is the unlock. Once I update to 4.1 I lose it. Too preserve the BB TinyUmbrella only works with th iPhone 4.
