Possible the store model was messed up, but what do you mean by "upgraded?" Don't all D2's come with 2.2 already installed. Besides, I gotta say it wasn't just a little jerky; it was genuinely unwatchable. I've since run across the review from LAPTOP magazine were the guy had the same exact experience as me, it sounds like. Seems like that's just the way it is unless the site is optimized specifically for Flash mobile. Not how I thought it would be. Requires a solid shift in expectations. Adobe or Motorola should have done something to manage those expectations better, I think.
