Why won't my iPhone turn on unless it's plugged in?
I purchased a used iphone but it won't turn on unless it is plugged in to the wall (it won't turn on if plugged in to the computer, and thus, itunes won't recognize it).
When plugged in to the wall, it shows the apple logo, and then immediately goes to the 'connect to itunes' screen. However, when you unplug to connect to itunes, the screen goes black and it won't turn on.
What do I do? Would a battery replacement help?
Es esta una buena pregunta?
