User your own known charger

[Glenn]

"Apple iPhones can be taken over with "alarming" ease using a custom-built charger, security researchers warn.

Using the bogus charger, a team from Georgia Institute of Technology managed to infect a phone with a virus in less than a minute.

Any device using Apple's iOS operating system would be as vulnerable to infection, claim the trio.

More details of their work will be given at the upcoming Black Hat USA hacker conference"

Presumably they'll be available from Amazon shortly.

I don't suppose it could be a ploy by Apple to get everyone to use their own highly priced chargers?
