After the iOS5 update (now on 5.0.1) I've been having problems charging my iPad 1 (as many others have). SOMETIMES I can get it to charge using a cable other than the $20 Apple one but usually it doesn't work. What gives? It used to work so these cables are clearly capable of handling the extra current the iPad draws. Also, my iPad refuses to charge via anything except the Apple wall charger after the update. I have non-apple 10w chargers that would charge my iPad at 2A before the ios5 update. Another weird thing: I can sometimes charge my iPad with the Apple iPad cable on a non-Apple charger. How can I fix this? I've just about had it with waking up to find my iPad hasn't charged to the point where I'm considering switching to Android and that will be very painful as I tried it already with my iPhone and had to switch back.
ALSO: I use USB extension cables running from my wall chargers to my bed and my iPad will NOT charge if I use an extension anymore (even if I'm using the included Apple charge cable on the end of the extension). It's really impractical having to be huddled up near a wall to use my iPad while it charges.
