O2 internet not working

[PowerFullMac]

I just restored my iPhone 3G coz it started randomly freezing, the restore went fine but it seems that my O2 internet service no longer works...

Any help, here? Is this normal after a restore? Do O2 need to set it up again? Should I have removed my SIM card while restoring?

D'oh! I forgot to change the interwebs APN to "payandgo." from "mobile."

All fixed now, sorry to waste time and space.
