It has been a few months since I tried to downgrade but I certainly did try and killed too much time in the process. Could you point me in the direction of some instructions?
It's fairly easy, just save your old SHSH blobs (I always jailbreak my device so I'm not sure if jailbreak is required, there's a tool called TinyUmbrella to do it), then you can downgrade to whatever version you want.
You can, but it is a hassle, and Apple certainly could have made it easier.
