on my blackberry, I left if on the roof of the car beofre proceeding to squirt water all oever it......
It worked okay for a day then died.
when I took it to the shop (dried out) to try getting a warranty jobby on it, he took out the battery and on the side was a small red stick lable abot 2mmx5mm which was red.
He pointed out that they are usually white until they get wet. and gave me the finger on the warranty.
But if you have an barclays additions plus account. or other banks may do the same, then your phone could be insured with them as mine luckily was. but i didnt know until a bloke in the bank pointed it out to me.
