I am having the same problem. Update went fine but when try to connect to wifi which was working before is not working. Tried several othe APs same issue. Tried rebooting, removing the battery it says unable to connect one or other account. Gmail/Gtalk does not work , skype says it is online.
Other issue : When I try to restore setting to original facotry setting says enter unlock code. I did not set this int he first place. I used ATT sim in the Nokia. How in the hell this release passed. Nokia is really testing the paitence of their loyals by screwing like this.
Any solution please?
