Carixma, can you clarify a little more. There are a few things that could have happened. You say your phone was jail broken, were you using it with t-mobile? If that's the case than your phone got locked once you updated the phone with a newer version. Anytime, you update your Iphone it will lock it so it can only be used with ATT. Again from what I have heard (not sure because I have never tried it), once it gets locked you can't use the wifi or other features unless you have ATT. The only other way to start using your wifi is to either sign up with ATT or have it jail broken again.
