I jailbroke my ipt4g with greenpois0n and I am now getting TERRIBLE wifi reception. Has any one else had this problem? I suppose I get good reception, but the ipod simply won't connect. Most of the time I have to forget the connection and set it up again for it to work. At work, using their wifi, it also brings up a login box which it did not do before and we have not changed our security policies/settings.
