I got this iphone4 from my friend with 4.2.8 loaded on it. I went to JBMe3.0 and cydia was installed. Then when I tried to run cydia it locked up and then showed the itunes with usb cable symbol. I had to go to vacation and in that 2 week period 4.2.9/4.2.10 came out. Now I need to restore this phone but I do not want to upgrade to 4.2.9/.10. I have blobs saved in TU for 4.2.8 and tried doing the restore using a ipsw. But I get a whole array of errors and I don't know what the official way of doing it is. If anybody can help me please let me know. I have NOT updated it to 4.2.9/.10 at all. Thanks in advance.
