anyone else have this problem: losing function of main control button which changes the applications/functions? when i turn off the phone and reboot, i now only get the phone pad. the local mac dealer said i got it wet and it has rusted out the connection for the power recharger. i don't remember ever getting the phone wet/spilling anything/it just stopped working. of course, now the warranty says no coverage. rats. the phone is less than a year old. suggestions please. thanks.
I could see corrosion from salt air, but not rust. Most computer parts manufacturers use connectors that are copper, aluminum or gold plated. None of those metals rust.
Rust happens to iron, or metals that have iron content. Copper, aluminum and gold corrode. It is represented by a white haze on the metal (for copper, usually green).
This can be remedied by using a dielectric gel on the contacts. Think of it like vaseline. It keeps the contacts from corroding and allows doesn't interrupt the transfer of power/data.
Of course, the contacts need to be cleaned before applying the gel. You may be able to find a gel that does both. If memory serves me right, I believe they have that now (been a while since I had to buy any).
