the phone was in 1.02, the wifi is gone suddenly. I can still turn on wi-fi, but it keep searching and couldn't list the available network (none is showing)
Trying to upgrade to 1.11 firmware, the same result. Now i can't unlock the phone anymore, coz there is no wi-fi, i can't even connect to putty coz it doesn't have an ip.
It's been a few months since i bought it, is it still ok to return to apple?
