Hey guys so i updated my baseband to 06.15.00 and firmware to 4.3.3 but now my wifi doesnt work. Its not greyed out or anything it just doesnt detect any networks. I stood right next to my router and still didnt get a signal. I get wifi on my ipod touch 4g on 4.3.3 and my laptop too. I tried downgrading to 4.1 (ony shsh saved) but it didn't work. Ive tried restoring multiple times and i have reset the network multiple times. Can anybody help?!
