On on a j/b'd 3GS running 3.0 now. Are these the steps for getting to jailbroken 3.1? 1. Download a custom 3.1 .ipsw that's been jailbroken (since I'm on Windows). 2. Do SHIFT + Update in Itunes to install it. 3. Done? How about some of the things I've seen/read about certain apps like cydia/winterboard not quite working on this version yet? Thanks!
