Im glad i wasnt only on the same boat. I have the exact problem with wifi even if i reset network settings. Did u try setting up vpn? I couldnt save the configuration no matter what i tried. I use vpn for installous as its is block here in my location. Thats why i decided to jump to 4.3.3. Although i tried saving my 4.3 blobs thru TU. it only saved 4.3.3 and 5.01b.
Tried resetting didn't work.
If I try to upgrade to 4.33 will I need to jb again and after will the wifi settings be normal?
Pls let me know?
