I tested an older version of Opera Mini, iirc 4.x, on an actual 00s phone (we still have 2G networks with no plans to shut them down) out of curiosity several months ago, and to my great surprise, it worked too. Exactly like it did back in 2007. And yes, there were those interstitial ads too. Those definitely weren't a thing in 2007.
