    Hello! greetings…

    I am confused step 9.

    Step 9: But no Cydia icon after reboot, do not worry, don’t touch your iPhone, over forty-five minutes, the phone automatically restart, iTunes & USB appears again, then click the button again,then you will see Cydia icon after the device reboot again, but still need to wait until phone respring. Wait a while, you can enter cydia, Congratulations, iPhone 4 is jailbroken.

    It says “…thenclick the button again,..”.

    What button do you mean here?
    What I did, was, I clicked the “Teether button ios 7 model 3.1″. I rans well but most applications and settings don’t work; Wifi, music and others.

    Now I repeat the process. I am now on step 9, at second reboot with itunes-USB logo.
    After 1st reboot without cydia the phone will reboot and pops up the itunes-USB logo. So you said I will wait for 45 minute to come back from itunes-usb logo.
