WP7 OS Version numbers

For my own reference and because I couldn't find anywhere else where this had been documented. Here are the different OS Version numbers for each of the WP7 releases/updates.

7.0.7004.0 - Original public release
7.0.7008.0 - "Pre-Nodo" update (contained changes to support the NoDo update)
7.0.7390.0 - NoDo (No-Donuts) update (included performance improvements and cut and paste)
7.0.7392.0 - Security update

Update: See http://www.microsoft.com/windowsphone/en-us/howto/wp7/basics/update-history.aspx


  1. As I already pointed out on DZone, there is also build 7003 for prototype phones (e.g. Samsung Taylor).

  2. Hi Den, Yes I know there were various version numbers for prototype and "developer mule" phones but anyone who had one (or access to one) is under NDA to not talk about them.

  3. Not really. Prototype phones were given away to PDC2010 attendees (at least some of them) and the 7003 build is well known among those. Its one characteristic is the fact that it is not update-able.
