So I jailbroke my iphone 2g (which was given to me after my dad got a new iPhone 3g) with hopes of using it simply as an ipod, not for cell phone service.
I used quickpwn with 3.1 firmware. The first think i noticed was that I didn't have wifi capabilities.

I know my routers working because my two computers have wifi at the moment.

I found somewhere online that I should reset the wireless settings. I followed those instructions, and now the Wifi section is grayed out saying, "No WiFi"

To my knowledge this is only happening to me. Is it possible its because I have no sim card? Should I unlock it also? And how do I unlock (I'm assuming I'd be using ultrasn0w) without wifi?

Thanks!
