So, I recently had this scare where I woke up, picked up my phone to check the time, and… was greeted by the “white screen of death”. No, this is not really death (or so I told myself as I hauled up my computer and got googling).
The queries returned several options, but this is the one that worked for me: simply hold down the HOME + POWER key SIMULTANEOUSLY and within seconds, your phone or iPod should reboot!
There are other threads out there with different solutions (such as holding down the volume up + home + power key simultaneously) , but those didn’t work for me.
And now you know!
