I've got a launch 3G iPhone, and it is acting increasingly odd. The issues are as follows: 1) Volume will change itself and "jam" at either the max or minimum. I can't turn the volume down at this point, as the phone is getting both vol up and down signals at the same time. However, after a while, it will eventually stop. 2) Random interludes of locking/unlocking/power down screen. It's as if the lock switch is sending signals to the phone, even when not depressed. This can frequently mean I can't use the phone for quite a while, as it's sitting there flicking away between locked/pin entry. Again, this eventually just stops of its own accord. Any ideas? The phone is out of warranty, although I'm thinking I may be covered under the UK Sale of Goods act, as the phone is obviously faulty and not functioning as expected. Water sensors are both white, as you can see.
