Hey there,
I have an iPhone 3G running iOS4.0, jailbroken with Redsn0w and unlocked with ultrasn0w. It's an American phone I imported into New Zealand.

My problem is I can't get the GPS to find a signal.
I've tried restoring and rejailbreaking, and i've installed Pushfix 2.0, which fixed my push notification problems, but the GPS still doesn't go.

Anyone have a clue whats wrong?
Getting desperate.
