For the last month or so, when I search Google from Mobile Safari over 3G, I have frequently (but not consistently) been getting the Sorry, weve detected unusual traffic from your network error page. Sometimes it has a captcha that I can enter, sometimes it does not. Sometimes when I clear the browser history and cookies the problem gets solved, sometimes I have to wait. I had never gotten that error before about a month ago. Has anyone else seen it? Figured out how to fix it? All I can imagine is that one of my apps or tweaks might be doing a lot of automatic Google queries that I dont know about. Are there any that are known for doing so? I can attach a list of my installed packages if that would help figure it out. I am running iOS 5.0.1 on a jailbroken iPhone 4s.
