Hello, In the past when I was running the 3.1 betas I was able to downgrade to 3.0 by restoring to 3.0 and running purplera1n when the 1015 error box pops up. I was curious if this is no longer possible. I haven't seen anyone talking about it and was wondering if something in the 3.1 GM changed to prevent this. Thanks for your input. EDIT: I imagine this wouldn't work because Apple is no longer signing 3.x?
