Sprint's Samsung Galaxy S III gets large update
The software version is L710VPMA6 and includes an update to the voicemail app, adds a feature to SMS and fixes an issue that prevented the calendar from syncing to other apps. Speculation is that the update also fixes a security exploit. This is the first update for Sprint's Samsung Galaxy S III since last October when Android 4.1.1 was installed. Most of the features from Sammy are found in Android 4.1.2 or higher.
