Hello chaps, I have a 3G running on 3.1.2 JB'ed with pwnage tool. I'm on O2 in the UK. I used the sinful tethering package in Cydia to enable tethering and have been using it faultlessly for a couple of months at least. I was sat on my MB Pro surfing the web using the iPhone tethering and suddenly I had no net access. Looking at my phone the blue tethering stuff had gone from the screen. I went into General -> Network and the toggle switch for the tethering has gone and now only has the "set up internet tethering" button. I have removed the sinful tethering package and reinstalled it with no luck, still no tethering option. I haven't updated the iPhone or backed it up, restored it etc and iTunes was closed when the tethering stopped. Any ideas as to why it suddenly disappeared and how to get it back? The tethering was the main reason for my jailbreaking so would really love to get it back. Thanks for any help.
