I recently got a iphone 3g from my friend and i redid the phone and restored it to the latest firmware, after that i tried to turn on the WiFi and it was greyed out. After that i jailbroke it thinking it might fix it and again it is still grayed out. I am stuck i dont know whats wrong with it. And i have no way of getting any other way of getting it connected to the network because i do not have att and i am using as a development device only.
