I doubt anyone knows for sure. The only thing publushed said it was due out 2Q2012 - which goes through the end of June. Then there's been discussion whether the RAZR will even GET the update ... so who knows?
Kind of want's to make ya hit head up against the Wall in a Silly kind of way. Because of the Back N Fourth thing that Motorola has Said in there statements b33
I read recently that the update is expected to hit by or before the end of June. Razr and Razr Maxx were in that time window. The Droid 4 will be between July and September and the Bionic will be sometime in July.
