Cseries :: C3-00 "Verification Of Server Certificate Failed

I bought the C3-00 a month ago and after several problems like phone attaching to the gprs on its own and firing all my credit, getting stuck for no reason when opening gmail with the gmail application, today I had to remove the battery for the first time trying to find out the security code - which no one set and which is supposedly "12345" by default (only not because it DOESN'T work) - because I wanted to reset it to the factory setting, the phone which two seconds prior that action - removing the battery - was connecting with no problems with my pc wifi now when opening the browser Opera is giving me the title error:

Failed to connect to the internet. "Verification of server certificate failed. Please check the date setting in your device"**bleep**?! I always thought about Nokia as a reliable brand, this phone is a MESS, bugs everywhere, and now this?!

A) I can't factory-rest the damn thing because I don't know the security code, security code which I never set. The supposedly factory code 12345 doesn't work.

B) After removing the battery the wifi is USELESS and the phone doesn't connect to the internet anymore. It goes to the nokia.ovi and the accuweather links and such, but the default browser (so ACTUALLY using internet)?? NO WAY..
