Λοιπον για οσους αναβαθμισαν καταλαθος σε 2.2.1 και το μετανιωσαν υπαρχει ενας οδηγος που θα βοηθησει:
★ Like everyone, my firmware was reading 2.2.1. So, I held down the Shift key on my keyboard and clicked Restore. I found the 2.2 ipsw file.
★ An error message popped. I don’t have an image of this error message. But, it said something about an unknown error (some number) occurring.
★ I ran QuickPWN 2.2.
★ The process jailbroke my phone. But, there were no contacts, music, email, movies, etc. saved.
★ So, I pretty much gave up and restored the phone from my 1/16/2009 backup. I’ve done this like 10 times over the past few days.
★ But, as the restore began on my jailbroken phone missing all my data, I noticed that the “Automatically sync when this iPhone is connected” box was still checked.
★ So, as my phone was restoring back to 1/16/2009, I went to Edit -> Preferences -> Devices and checked “Disable automatic syncing for iPhones and iPods.”
★ This checking of the box interrupted the restore and sync that was being communicated between iTunes and my iPhone.
★ The interruption allowed the jailbreak to remain in place (I had access to Cydia), my firmware to revert back to 2.2, and my iPhone 3G to retain all its music, movies, contacts, email, text messages, etc.

★ But, I didn’t have cellphone signal - only WiFi - and my clock was 2 hours behind. It was 4:50+ am and not 2:50+ am.
★ So, I restarted my computer and iPhone and restored (shift + restore) again from the .ipsw file and ran QuickPWN 2.2 again.
★ I had all my music, contacts, emails, text messages, etc. and cellphone service after restoring to the backup I saved earlier in the morning. My clock caught up as well.
The following is a final screenshot of my jaibroken iPhone 3G before I look off for work…
Yes!
P.S. Yes, I have some really random Apps from the AppStore. I’ve deleted many of them - e.g. Google Earth - several times but the back-ups always restore to my previously installed Apps. I gotta take care of that one of these days.
Υ.Γ:Αν θελετε να κανω μεταφραση πειτε το μου αν και δε νομιζω οτι ειναι δυσκολο.

Έκανα update σε 2.2.1. για να διορθώσω μια βλακεία που έκανα (διέγραψα καταλάθος κάτι αρχεία από μέσα), ακολούθησα ότι μου έλεγε ο οδηγός αυτός αλλά δεν μπορούσε να μου περάσει με το QuickPWN το 2.2 γιατί το τηλέφωνο είχε την 2.2.1 και σταματούσε. Ξέρει κάποιος αν υπάρχει άλλη διαδικασία για να το κάνω downgrade? Α, και στο 2.2.1 δεν μου δούλευε σωστά το WinterBoard, δεν έδειχνε τα ονόματα στα προγράμματα και στα παιχνίδια.
