hi all. thought this might help someone? my phone died yesterday. it was playing up a couple of weeks back. charged but other than that usb connection didn't work. no internet for the lap top and no cable file transfer. also didn't like turning off and just kept re-starting. looked on line for a solution and found the problem - moisture in the usb slot slowly corroding it's way in. apparently not uncommon problem. the fix was a scrub with a small wire brush and I sprayed some lanotec in there too. got my connection back but only for a week. then I took it to a repair joint and paid $20 to be told it was stuffed. all up it lasted 14 months and maybe it's time in the salt air sped things up but I don't believe I ever got water in there. so keep an eye on your usb ports or spray them with something now and then and if you get any of these symptoms - back up your phone! I didn't and am starting from scratch again...
