weird WI-FI issue - quit working with newer firmwares
Last year I got a 1.1.2 OTB UK iPhone. I've never been able to use wi-fi with this firmware. Out of desperation I downgraded to 1.0.2 and everthing worked flawlessly. Unfortunately with newer firmwares I've never been able to get wi-fi working again.
1.0.2: wi-fi worked flawlessly
1.1.1 - 1.1.4: could see available networks but was never able to join one
1.2.0 & 1.2.1: can't see any networks at all
Since it was working with 1.0.2 I don't think it's a hardware fault.
Can someone point me towards the root of this problem?
Any help would be greatly appreciated!
