probably a repair job, although maybe dry it out and cross fingers
dropped my iphone in jacks a while ago. thought it was fried. sent to to Apple , chance me arm, they sent it back saying 'external water forces' caused it . must remember that one next time i do it
anyway was almost not even gonna collect it coz i thought once the aul smartphones got any liquid in them they were toast, but anyways tried it before chucking in the bin and low and behold it turned on and has worked perfect every since.
so moral is , if ya leave it a bit , ya never know . failing that, probably a repair job should do it , looking at e70-100 im guessing
