Hey everyone. I'm kinda new to jail breaking and I currently have an iPhone 4 running 4.1 and is jail broken. I want that mobile hotspot feature on my phone but I'm not sure if there is a jailbreak for the latest iOS 4.3.1. Is there? If not, is there a way to get that feature by jail breaking? I think I remember people getting game center through a jailbreak without having to update their software and losing their jailbreak. I know about this alternatives like myfi (I think that's what it is called...), but I am just wondering if I can get the actual thing. Any help would be appreciated. Thanks!
