I wonder if it is just a coincidence, but my wifi download speed was 30 Mbps after I upgraded to iOS 6.0.2. Before that, I never seen it above 10 Mbps. Nothing else changed afaik.

There's a similar thread about this topic in the iOS 6 forums, where other users have similar experiences like you. After all, the only thing the update is supposed to fix is the wifi problem, naturally the performance of it is expected to be better after the update.
