How were you able to downgrade? Is it because you didn't use blackra1n?
correct. I have been jailbroke since 3.0 and have waiting patiently for the next JB
Update: it has been about 24 hours, not really much done, mostly standby and I am only at 80%. Did about 25-30 minutes of internet/gaming. So it was def something to do with the 3.1.2 JB (if not the entire software). Not sure what it was but i am back to being perfectly happy with my iphone.
