I accidently put 3.1 on my 3GS (my 3G can run betas, not my 3GS) and now I can't use 3.0, 3.0.1, or 3.1. When attempting either 3.0 or 3.0.1 I get the error 1015. When trying to restore to 3.1 it tells me I'm not registered with the DEV team. I really need some help here. I don't want to jailbreak my 3GS.
