So, before the 4.2 update, I could go (iphone 4) to settings/Safari and see a link to Databases, which is where an advanced type of tracking cookie is kept. I had a gmail one, plus some RLDGUID one that's been controversial (see other threads) due to its persistence. But you could always swipe your finger on one of those and kill it. But now with 4.2, we not longer have that option. Nice. NOT. I do wonder though if perhaps the functionality to erase these cookies is now subsumed under the regular "delete cookies" button. Can any web devs confirm whether this appears to function this way now?
