This just in – our tracking software informs us that more than 60% of our iPhone customers have already upgraded to software 3.0.  That’s pretty fast.  Personally, I haven’t done it yet… one of my office mates was complaining about it being a tough transition and I always like to wait until I hear the complaints die down… I didn’t get the 3G iPhone, for example, until they were on software release 2.2.

We’re doing a ton of stuff to support 3.0.  Some of the first features we are supporting are the iPod music library and push notification.  We’re also going to have friends leaderboards and other social features.  We’re especially excited about microtransactions and have some big plans that will unfold as the year progresses.
