Jailbreak

[paughh.1]

Do I need to downgrade my I Phone 4 with IOS 5.1 and 4.12.01 firmware. My phone was jail broken before. It had to be restored by apple and now has the IOS 5 instead of IOS4. Thanks in advance

You must download Tiny Umbrella, save it to your desktop

Plug in your iPhone
Open Tiny Umbrella
Click the "Save SHSH" button.

If iOS 5.0.1 shows in the list in big white box, then you can restore to iOS 5.0.1. But must do a few thing before attempting to restore.

There's no need to downgrade... unless you truly want to. iOS 5.1 offers many, many advantages over any version of iOS 4 you could have been running. The only downside you'll find, at this point, is that there isn't an Untethered JB for iOS 5.1 yet. You can, however, JB Tethered w/ the latest version of redsn0w.
