I get "Charging is not supported by this device" w/nothing attached
Contaminated my iPhone 3GS with a mixture of oil, sugar, soy sauce. (Korean BBQ Marinade)
Not much but just enough to cause the message "Charging is not supported by this device" when ever I wake the phone from sleep.
Everything seems to work and it will charge. The message goes away when the docking cable is attached.
What do I do as the Apple "Genius" told me I'm sol unless I want to pay full freight on a new phone.
Is this a good question?
