i had a third party mobile repair technician inspected on my x10.
it the weak micro usb port caused the problem of charging.
my situation is that i brought the x10 oversea before it is officially launched in the U.S.
Now i understand that SE will CHARGES me hundred bucks to repair. but the length of time to get it back from SE will freaks me out completely.
One of My friends she has similar situation and sent it back to SE from U.S. she took nearly 3 months to get it back.
