The last time I used my iPhone 4S when I was awake was 3 hours ago. It's currently 3.14 AM as I'm typing this and I need my iphone 4S to wake me up around 6.40 am for class. I wake up randomly to find my iPhone stuck on a black screen with a spinning wheel. I hold onto the power button sand NOTHING happens. I do tried holding onto the power button for 5 minites. NOTHING HAPPENS. The last thing I remember doing, was leaving my phone on to go to "sleep" while on default alarm clock app. Can't believe it.. but i guess the iPhone is capable of errors after all! First thing i've ever had a defective iPhone. Any tips on what to do while I google a solution? Or do I have to wait for the battery to die and stay up for 3 hours? This iPhone is less than a month old.. is it defective? Should I return it for new model?
