I do not own a Blackberry, but there appears to be some confusion as to whether a Blackberry is waterproof or not. In 2008 Blackberry seemed to say that they were waterproofing their devices, and at the same time placed a sticker inside the units, which should change colour if the unit was dropped in water. This was done for warranty reasons.
Looking on the internet, some people seem to say that they have dropped their Blackberry down the loo, in a sink full of water, and all as worked fine. Others have mentioned that theirs got wet in a rain-shower, and theirs didn't work afterwards.
The attempt at drying seems fair, providing to much heat wasn't use, just 'gentle' heat.
I suppose the next step, is to reassemble, then try it out. Failing that, call the customer care centre!.
