i have a no wifi problem, but this I suspect is due to software malfunction. ever since it has been unlocked to 3.0 the wifi does not detect any signal even when i am directly beside the router.

restoring it to 3.0 though itunes does not work, same problem.

would i need to change the logic board or just the wifi chip.
