Der etwas andere iPhone-Blog

PowerWiesel:

I’ve got an other way for 3gs and older
If not already powred on, turn it on and press, whenever, the following keys;

Home + Power –> until the screen flickers,
then release Power, but keep Home holded until “something happens”.
For example iTunes reports a device at restore mode, at first time and if u use another usb-port a new driver will be installed and generally the pc is works for a few seconds.

This way always worked for my friends

PS: @ iPhone 4 its the same, but the screen doesn’t flicker.
U have to hold
Home + Power –> until the screen is black for a second.. (holding for 7-8 sec, if the apple is shining, you have pressed,maybe a bit, too long)
.. and then release power, keep home holded…… as above.
