Well, yesterday my HTC Hero plunged into a bucket of water for about 5-6 seconds. I stripped the cover, battery, and cards and left it to dry for about 4 hours (there didn't seem to be much water ingress!). Turned it on and it boots into life, woo hoo! Thought I'd got away with it but noticed that it was permanently in 'headphones' mode, so phoned provider as it was fully insured for such an idiot using it
Got a new one arriving tomorrow evening, and now -
given a little more time to dry out - this one is working just fine!
As much as I love this phone, I was kinda hoping they'd run out of Heros and would have to give me something a bit newer
