I have an iPhone 3G which (after too many drops floor) doesn’t have a working sleep button. The button still “clicks” so it seems like it is something else. I did take the phone apart and put it together again with no luck. Do anyone of you know what I could do and/or what parts to replace? I did the mistake of upgrading to iOS 4 to jailbreak it (not sold in my country) but I’m not able to without getting into DFU mode, which needs a working sleep button, soo I have an expensive device which only displays the iTunes logo :s Thanks, Gunnar Steinn
I had the same problem with my 3G. What I ended up doing is buying a new headphone jack to replace the old one. The button that the power button knob presses against is attached to the headphone jack. I bought it for about $9 on eBay. The power button functioned again after installing the new headphone jack. The guide to do this is found on the ifixit website.
