It looks like Motorola is going on a roll here. Right after they finished the soak test for the Droid X2, they got another one out and this time it is for Sprint’s Photon 4G. If you aren’t one of the testers and want to get your ‘MoPho’ updated, you may have to wait up to a week or less, depending on if they don’t find any issues with the new build.
This new update will bring your build to version 45.3.6 and will fix the video chat feature on Google Talk, add Moto’s social location app and addresses a bug with the proximity sensor. If you don’t like to wait, you can probably find a leaked version somewhere at the XDA Forums.
