Does iOS 4.2 improve performance on the iPhone 3G? I've "inherited" an iPhone 3G from a friend who upgraded to iPhone 4. He had complined about the slowness of iOS 4. Although I personally have no problems with it, I was wondering if iOS 4.2 offers any noticeable performance improvement. Does iOS 4.2 improve performance on the iPhone 3G?
From the iLounge article


  Thus far iOS 4.2 appears to perform as
  well as iOS 4.1 did under similar
  conditions. Performance even on older
  devices such as the iPhone 3G is the
  same as iOS 4.1 and thus far we
  haven’t observed any significant
  changes in battery life.
