The remaining details of Dell Streak's release continue to trickle out. This morning we learned it would eventually run Froyo. Now we know the price: $299 with a 2 year AT&T contract or $549 unlocked. Updated
Despite blogs, rumors, etc., Dell has not made any official #dellstreak or Aero announcements today
This doesn't necessarily mean that the $299 and $549 price points are incorrect; they're just not 100% totally official quite yet.
All of this comes right from Dell themselves, but what's still unclear is when you can get one.
