And of course, it had to do this in the middle of the afternoon on the long weekend when everything was closed. Not that there was any phone call I particularly needed to make, but I am rather fond of its picture-taking capabilities.
This morning, I took the phone into the Telus store and in less than a minute the lady there worked her magic. I didn't see any mention of this magic trick when I plugged in variations on "why is my idiotPhone dead?" online to find out what the problem might be and how much this was going to cost (lots, it appears -- when no one quotes even a ballpark figure, you know you're in trouble) and I was afraid, very afraid.
The magic trick is the ALT-CTRL-DEL of the phone world: press the top OFF button and the bottom ON button at the same time and hold. Maybe 8 or 10 seconds later -- if the battery is still alive and not dead because you dropped it -- the white apple will appear, it will reboot itself and Bob's your uncle.
The Telus lady said that sometimes there's a arbitrary glitch for no reason and it just wants to reboot. I also read that a typical phone battery is good for 500 charges. I've had mine for just over two years. So a charge every two to four days, take my socks off here........... At most, that's 300 charges.
Now we know.
