Sprint just updated its support docs for the Samsung Conquer 4G with details of a new OTA update set to begin rolling out at any moment. It's a rather small and nondescript update that just brings a couple of fixes and enhancements:

Enhancements/Fixes:

• 4G Modem Update - not customer impacting 
• Lock screen changes - swipe in any direction to unlock

Like I said, it's minor. The update should begin rolling out today or tomorrow and will complete its rollout process within ten days.
