Iphone 4 dropped no wifi
Have an iphone 4 that was dropped (thrown very hard actually), and now wifi is greyed out and bluetooth is spinning.
I've checked voltages and have both battery and 1.8v, there is no broken lines.
I reheated the wifi chip but made no difference.
I don't think it's a definate check, but I measured resistance on Y2_rf crystal and am getting different results to a known working board.
Is there a way to check the crystal?

You may have caused more harm, than good heating ic, will need to be reballed, check around ic's for cracks in glue/epoxy.
