I saw other post on this same prob for 2.1 but does anyone have a solution for 2.2.1? I am using the 2g iPhone quickpwned with 2.2.1 and I have installed miPatch Firmware 2.2.1. I want to upgrade to 3.0 but get the "could not back up " error everytime I try to backup. I refuse to set up phone as "new phone" I would rather stick with 2.2.1 than lose all of my data. Suggestions?
After thinking about this some more does anyone know if maybe I just delete all of the cracked apps off of itunes and my phone and uninstall miPatch maybe it will work? I guess I can try its just easier if someone else has done this and could answer.
