So For now it is impossible to Downgrade to 02.28.00 coming from 02.30.03 Because for the 5.9 BL

After going through some threads and reading about the iphone 3g downgrade that some of the people with 5.9 where able to downgrade and i could not
had me test most of the forms of the downgrade
i did the one that i was the most comfortable with

  1. Patched the BB myself
  2. DownBB from iClarified
  3. 3GBBD form BossPrefs (i think)
  4. phdowngrader (have not tried it yet i will in a little while

Now This Thread is to keep an update or updates on the 5.9BL Downgrade.

So people with the same thing post your failures and successes
