I unknowingly plugged my corroded I-trip into my I-phone, which now doesn't even turn on. Genius bar says the corrosion is water damage (it isn't) and won't help. They say even if it is just corrosion, that's not a hardware problem, so they won't help. Do I have any recourse? And is there any way I can turn on the phone long enough to at least wipe it clean? Thanks!
