So a year and a half or so into owning my iPhone 4, my power button has stopped working. I understand that this is a not unheard of problem. I will attempt to take it back to Apple, but I'm well past the warranty stage. I did not drop the phone and it has no signs of abuse, but my habit was to push the phone off every time after use before putting it in my pocket. Anyway, I haven't made it to the apple store yet. So far not having a power button hasn't been a problem. In the past, powering down was a necessary feature for nights where I didn't make it home to a charger. But I'm settled down and don't have those types of nights anymore. If I have to do a long flight, I can put the phone in airplane mode and conserve battery so at least it isn't searching for a signal. Can anyone think of any issues I might have without having a power button? My plan was to hold on to this phone until iPhone 5. But I am also eligible in a month for a new phone, so I could get iPhone 4S for $200. Do people think that it is likely I will need to do some sort of reset and not be able to do it without the power button? If Apple won't fix this for free, I might try to hang on for the next seven or so months for iPhone 5. But if I'm just tempting fate, maybe I should replace it. I do not have a land line at home and the phone is also used for work email, so it is "mission critical" and prudent for me not to take chances.
