So, I do a lot of rooting(androids), jailbreaking(obviously idevices) for a local cell shop. Mostly software work in general. Yesterday my guy brought me a iPhone 3G, on 4.0, with a unlock able baseband. When I got home I noticed wifi was grated out. Basically I need the Internet to DL ultrasn0w in Cydia, but neither of us have access to a AT&T sim card ATM. So, I restored to EVERY ingle firmware that I could DL, I think I went back to 2.x maybe lower... I mean literally 10 or more firmwares, even upgraded to 4.2.1 with pwnage tool or whichever one preserves BB(I can't remember, I've tried so many things)... My problem is this, in settings, where wifi would usually be, it just says no wifi, and is grated out. if you go deeper into settings into about, under wifi address it says N/A. I've googled the ever loving **** out of this. It seems to be very common issue with the iPhone 3G. I've also searched the **** out of these forums for a answer. So my question is this: Does anyone no of an actual fix? Lots of apple support forums claim its a hardware failure, but I've seen it before when upgrading a 3G past iOS 3, basically 4 or above. But it always managed to basically fix itself after multiple restores or a reboot or evn a hard reset. I'm just totally stumped on this, I've read some stuff that says the only fix is to restore back to 1.xx but I don't think I can even do it on the 3G, even if I cud an itmfixed the problem, no one would buy the phone as the older versions are missing so many features ppl expect. Stumped, sorry for rambling on.
