I just got a 2g 16gb unlocked and jailbroken. The wifi selection is Greyed out. And can not turn it on. Looked on line and did a reset network settings. Did not work. The next step is to erase all content and setting. And the third is to restore the iphone with my itunes. I and in Afghanistan and don't want to loose the unlock/jailbreak feature. Will the second and third option lock my phone. Or are there any other things I can try.
