Thread: Jailbroken 3G with IOS 4 and no wifi - what to do?

    Default Jailbroken 3G with IOS 4 and no wifi - what to do?
    I've been using my iPhone 3G with IOS 2.0.2 and turbosim on T-Mobile and foolishly decided to upgrade to IOS 4.0 / 05.13.04 baseband
    I Jailbroke it with RedSn0w but I can't make much progress in unlock because wifi is not working anymore (does not discover networks, when I enter SSID/password manually it says 'cannot scan for wireless networks'). Turbosim is not working with the new baseband so I can't make calls.

    (1 hour later - found solution!)

    I found a simple solution posted by CincinnatiKid here: http://modmyi.com/forums/redsn0w/715...edsn0w-jb.html

    Basically, there is a PC version of Cydia called Cyder. I downloaded the needed packages on my PC and transferred to the iphone via USB cable. It took me 5 minutes to do the whole thing! Here are the detailed instructions:

    Thanks for your post it will be useful. I had a similar problem as yours with
    a 3G last week and found that if i stood next to the router the wifi worked. So was able to do the unlock. It seems the 3G issue on wifi is signal level related.
