If you're making use of a Motorola Milestone X on CSpire we have some good news for you all. Yesterday, the carrier started to roll out an Android 2.3 Gingerbread update to the device which has been long awaited. Most users should get an update notification but if not just go to: Home>Menu> Settings>About Phone>System Updates
After that, you should find the update available for download and installation. Once updated, you'll find all the normal Android 2.3 goodies as well, a newer version of Blur.
