So I recently purchased a milestone (from china) and I'm now using it on at&t's network. Unfortunately, today, when I tried to boot up my milestone, it wouldn't start up and there is no screen at all. I hold the power button, but there is no response at all. I tried taking out and putting the battery in and using the wall charger to recharge it. However, the white charging light doesn't even come on and after leaving it charging for 2 hours, nothing happened.
