Saw your Tweet about O2 content lock, they do charge £1 but you get £2.50 credited back to your account. Google Translate is a tricky one for mobile companies because it acts as a proxy so you can get to any adult site through it. The regulators are to blame not the operators. Easiest way to fix it is pop in an O2 store and ask to be unlocked.
