iPhone compass/GPS not working...


My iPhone3GS GPS/compass doesn't work. In the maps application the locate button doesn't secure a lock. The compass application shows 0 deg at all times.

Have tried restoring to 3.1.2 but doesn't help. Looks like a h/w problem. Any pointers?

Has the phone ever been taken apart before? You may want to make sure that ribbons 6 & 7 are properly seated in their spaces.

Nope, its never been taken apart. It used to work perfectly fine. I got the 3GS in July of 2009. The GPS and the compass were always accurate. Just wondering, if the compass doesn't work will that make the GPS fail too? What are the chances that both the chips (the chip for the compass and the GPS chip) have failed at the same time?
